+1 for E

Negating E shatters the conclusion "the decisions were correct only about half of the time".

The conclusion above depends on the presupposition that

Pre-thinking:In what scenario the conclusion made by the consulting firm is wrong.
1. what if it was not possible to clearly define a decision as correct or incorrect. Assumption: It is possible to define a decision as correct or incorrect.
2. what if consulting firm's criteria for defining correct or incorrect was not along the lines of what the clients criteria is. Assumption: The consulting firm's criteria for defining correct or incorrect decision matches the criteria of its client.

(A) companies can be successful even when about half of the decisions they make about marketing prove to be wrong.Irrelevent. We are not concerned about success of the company

(B) companies hiring her consulting firm make no more incorrect marketing decisions than do companies in generalIrrelevent

(C) executives consistently making correct marketing decisions rarely enlist the aid of a consulting firm.Irrelevent

(D) marketing decision are just as likely to be correct as they are to be incorrect.irrelevent

(E) it is possible to classify a marketing decision properly as being either right or wrongcorrect

(E), during prethinking the assumption, I questioned whether the president already knows the objectives for which the decisions where made in order to evaluate them!

Also Negation test shatters the conclusion.
