A television commercial describing why sure antiperspirant works better than right guard antiperspirant is an example of primary-demand advertising.

The answer is false. Primary demand advertising is any kind of marketing that fuels the chief demand for an item for consumption. Primary demand advertising instructs the consumer base about the aids of a whole product class but in the question it doesn’t. In the problem it is a selective demand advertising. It pursues to indicate the advantages of one brand of product above the products of rival companies.
