The premises don’t establish that a TV show would be canceled “unless one took certain actions.” Although a TV show would be canceled “unless people generally” buy the products, that doesn’t mean each individual person needs to buy the products in order to save the show.

Out of the five answers, (B) is the one the argument most closely matches. The premises establish that a TV show would be canceled “unless people generally” buy the products. So, since the show would be canceled unless a lot of people (”many”) buy the products, then everyone who want to preserve the show should buy the products. (B) connects the premises’ reference to people “generally” buying the products to why each individual person who wants to preserve a show should buy the products.

The argument concerns people who feel that a show is worth preserving. But whether a show is actually worth preserving is a separate issue. So (C) doesn’t match the argument’s reasoning.

(D) would support a conclusion that people who feel a show is worth preserving should take some kind of action to reduce the chance the show will be canceled. But it doesn’t support the conclusion that a specific action — buying the advertised products — should be done by every single person who wants to preserve the show. (D) leaves open the possibility that it’s OK for some people to take other actions, such as watching the show or publicly praising it, but don’t need to buy the advertised products.

(E) allows a conclusion that the people who feel “most strongly” that the show is worth preserving should buy the products advertised during the show. But the argument concluded that “anyone” who wants to preserve the show should buy the products. (E) doesn’t capture the broader scope of the author’s conclusion.
