Critical Reasoning

No one who lacks knowledge of a subject is competent to pass judgment on that subject. Since political know-how is a matter, not of adhering to technical rules, but of insight and style learned through apprenticeship and experience, only seasoned politicians are competent to judge whether a particular political policy is fair to all.
A major weakness of the argument is that it
(A) relies on a generalization about the characteristic that makes someone competent to pass judgment
(B) fails to give specific examples to illustrate how political know-how can be acquired
(C) uses the term "apprenticeship" to describe what is seldom a formalized relationship
(D) equates political know-how with understanding the social implications of political policies
(E) assumes that when inexperienced politicians set policy they are guided by the advice of more experienced politicians

My answer is D. What is the OA?
