c. 
concise

all of the above

The correct answer is D. All of the above

Explanation:

An academic argument implies one position or thesis statement that is defended and proved using evidence such as scientific articles or statistics in a formal academic context. Considering in an academic argument, the thesis statement or main claim is the focus, this should be always disputable as if it is a fact or accepted by everyone then there is no point in trying to prove it; also this should be specific because it should address only one aspect of a broad topic or issue; and, finally it needs to be concise as it should be only one statement or sentence. Thus, all of the above (specific, disputable, concise) are characteristics of an effective thesis statement for an academic argument.
