This question asks whether a society can keep growing richer while its population expands without limit, or whether unplanned population growth eventually undermines prosperity.

The question assumes population growth and prosperity are in tension, when growth can fuel prosperity through a larger workforce and market, so the real variable is whether growth is matched by resources and planning, captured by the word 'uncontrolled'.
conditions: prosperity and population growth can reinforce each other when growth is matched by resources, jobs and infrastructure, but 'uncontrolled' growth that outruns these turns the same population into a drag on prosperity.
How to approach it. Calibrate how far prosperity is compatible with uncontrolled population growth, defining 'prosperity' and 'uncontrolled' and distinguishing population size from its growth rate and management.
Population growth and prosperity can go hand in hand when growth is matched by resources, jobs and infrastructure, but the word 'uncontrolled' is fatal to the pairing, because growth that outruns a society's capacity to feed, employ and house it converts a potential workforce into strained services and falling per-person prosperity, so the answer turns on management, not numbers.
Forecasts that population would outstrip food have been wrong before, as the Green Revolution and successive technologies raised output faster than population grew, so the assumption that growth must outrun resources is not guaranteed. This has real force, and pessimism about population has a poor track record. But these gains came through deliberate innovation and investment, which is to say through control and management, so the historical record argues that prosperity survives population growth precisely when growth is met by planning, not when it is left uncontrolled.
Prosperity and population growth can go hand in hand as far as growth is matched by resources, jobs and infrastructure, but 'uncontrolled' growth that outruns this capacity dilutes prosperity and strains the environment that sustains it; Singapore shows both that management can stretch the limits and that too little growth harms prosperity too, so the answer is that the pairing depends on control, which is exactly what the question excludes.
The question hides a crucial ambiguity in 'prosperity': uncontrolled population growth can readily expand total prosperity while reducing prosperity per person and concentrating it among the few, so the honest answer is that the two go hand in hand for aggregate measures and the wealthy, and pull apart for the average person and the poor, which means the question cannot be answered without asking prosperity for whom.
If growth truly outruns water, food and ecological limits, no distribution can save prosperity, since there is not enough to share, so it is too neat to reduce the issue to distribution and ignore absolute scarcity. This is fair: there are real physical ceilings. But even those ceilings are reached faster or slower depending on management and technology, as Singapore's water engineering shows, so the distribution-and-planning lens still governs, because how a society manages growth determines when, and whether, the absolute limits bite, which returns the question to governance.
Prosperity and uncontrolled population growth go hand in hand for aggregate measures and for those positioned to capture the gains, and pull apart for the average person and the poor, so the question cannot be answered without specifying prosperity for whom; the real determinant is not the rate of growth but whether a society plans for and distributes its gains, which is precisely what 'uncontrolled' fails to do.
Option A calibrates by conditions, the pairing holding when growth is matched by capacity and breaking when 'uncontrolled' growth outruns resources, with low fertility as the opposite danger. Option B rejects the premise by interrogating 'prosperity for whom', arguing growth can expand total prosperity while diluting per-person prosperity and concentrating gains, so the real issue is distribution. Both are defensible: A is the measured matched-versus-outrunning calibration; B is the premise-rejecting move that reframes the question around who benefits.
