I am going ahead with E though B is a close contestant.
B is already there in the word 'using the same concept'. I donot see any requirement for that to be assumption. However, to have a jump(the main point, I believe) in sales, the existing customers should not be lost. Thus, E looks better.
Negate E - it means that some customer base is lost. So, we just cannot say whether they make any profits. Depends on the volume of business by upper class. Thus, the argument falls apart.
Negate B - An upscale clientele would not be interested in a housewares catalog. They may just have a look at the catalogue and still not buy any clothes. Does it give any assurance to sales jump? I donot think B is giving any assurance to sales.
A mail order company recently had a big jump in clothing sales after hiring a copywriter and a graphic artist to give its clothing catalog a magazine-like format designed to appeal to a more upscale clientele. The company is now planning to launch housewares catalog using the same concept.
The company's plan assumes that
A) other housewares catalogs with magazine-like formats do not already exist
B) an upscale clientele would be interested in a housewares catalog
C) the same copywriter and graphic artist could be employed for both the clothing and housewares catalogs
D) a magazine-like format requires a copywriter and a graphic artist
E) customers to whom the old clothing catalog appealed would continue to make purchases from catalogs with the new format
