This question asks whether advertising is mainly about getting people to buy things they do not really need, or whether it also informs genuine choices and helps define what counts as a need.

The statement assumes a clear line between needs and wants and assumes advertising mainly manufactures desire, when much advertising informs real choices and 'need' beyond survival is socially defined, not fixed.
degree: advertising both informs and manufactures desire, so the live question is how far the manufacturing of unneeded wants dominates, and whether 'need' is even the right measure.
How to approach it. Judge how far advertising's main purpose is to sell the unneeded, defining 'need' and 'largely' and separating informing from manufacturing desire.
Advertising does much of what the statement says, manufacturing desire for things people would not otherwise want, especially through sophisticated targeting; but 'largely' overstates it, because a great deal of advertising informs genuine choices and the category of 'need' is too narrow to judge by, so the statement is partly true and rests on a contestable measure.
Advertising is paid to move product, and a firm gains nothing from a customer who buys only what they strictly need, so the economic logic does point the whole industry toward expanding demand beyond necessity, which is real structural evidence for the claim. But 'the system rewards selling more' is not the same as 'advertising is largely about the unneeded', because expanding demand includes informing people of genuinely useful products they did not know existed, so the profit motive drives both honest information and manufactured desire, and the statement collapses the two into one.
Advertising does manufacture desire for things people do not need, and modern targeting and the cultivation of dissatisfaction make that real and growing; but 'largely' overstates the case, because much advertising informs genuine choices and 'need' is too narrow a measure for socially defined consumption, so the honest verdict is that advertising is significantly, not largely, about the unneeded, and the better criticism is that it manufactures dissatisfaction rather than merely sells surplus goods.
The statement rests on a false binary between needs and wants, because beyond bare survival almost all human wants are socially constructed, so advertising does not persuade people to buy 'what they do not need' as opposed to what they do; it participates in the social construction of what counts as needed, which makes the question's measure incoherent rather than merely overstated.
There is a hard core of genuine needs, food, shelter, health, safety, that is not socially constructed, and a great deal of advertising plainly pushes consumption far beyond that core, so the need-want distinction is not entirely empty and the statement is gesturing at something real. But almost no serious advertising targets that survival core, which is largely met, so judging the whole industry by a line that applies only to the rare destitute case misses what advertising actually does in a developed society, which is to operate in the vast constructed-need space where the binary breaks down, so conceding the survival core does not rescue the statement's measure.
Advertising is not largely about persuading people to buy what they do not need, because beyond a small survival core the line between need and want is socially constructed and advertising is one of the forces that constructs it; so the statement judges by an incoherent measure, and the question worth asking is not whether advertising sells the unneeded but whether the wants it helps create serve people or exploit them, which is where Singapore's focus on harm and vulnerability rightly lands.
Option A accepts the question and calibrates degree, advertising both informs and manufactures desire, so 'largely' overstates a real phenomenon. Option B rejects the need-want binary, arguing advertising constructs social needs rather than selling against them, so the measure is incoherent. Both are defensible: A is the balanced 'how far' answer a marker expects; B is the sharper premise-rejecting move that scores if the constructed-need argument is sustained.
