Marketing consultant: Last year I predicted that LRG' s latest advertising campaign would be unpopular with customers and ineffective in promoting new products. But LRG ignored my predictions and took the advice of a competing consultant. This season' s sales figures show that sales are down and LRG' s new products are selling especially poorly. Thus, the advertising campaign was ill conceived. The marketing consultant's reasoning is most vulnerable to criticism on the grounds that
A: it confuses a condition necessary for increasing product sales with a condition that will ensure increased sales
B: it takes for granted that LRG's sales would not have been lower still in the absence of the competitor's advertising campaign
C: it fails to consider that economic factors unrelated to the advertising campaign may have caused LRG's low sales figures
D: it takes for granted that in LRG's industry, new products should outsell established products
