Densmore Company, known for its luxury goods, has recently

DC (a luxury brand) wants to expand and market to consumers who usually purchase products priced at or below the prevailing market rate.
Plan: Attract them by advertising 30% off on their inexpensive line
DC has determined that advertising is the most effective way for them (best reach)
Goal of the plan: Attract consumers who usually purchase products priced at or below market rate

Evaluate the likelihood that the plan will achieve its goal.

A) How the profit margins on the new product lines compare to those for the top selling luxury items.

Profit margins have nothing to do with our goal.

B) What percentage of existing Densmore customers are included in the consumer survey.

Irrelevant. We are not concerned with current customers, neither with all consumers surveyed. We are only concerned with those surveyed consumers who said that they purchase products priced at or below market rate. The current consumers would be luxury good consumers. The advertising is targeting the people who buy at or below market price. The overlap would be little.

C) How many consumers surveyed are existing Densmore customers.

As discussed above, irrelevant.

D) Whether those consumers most concerned with bargain-hunting will be exposed to Densmore's advertising campaign.

We don't know who "consumers most concerned with bargain-hunting" are. It may not be the same as the "consumers who buy at or below market price". Our target consumers may not be MOST CONCERNED with bargain hunting. Besides, we have already found that advertising is the most effective way. How effective it is, is irrelevant.

E) How the sale price compare to those for comparable, non-discounted products.

Our target consumers buy at or below market price. We need to see if DC products after 30% are at or below market price. If other products on the market are still lower priced, we may not get the consumers we want. Hence, we need this info.

Answer (E)
