The answer is A: Rough drafts consist of an introduction, a body, and a conclusion.
A rough draft is a version of a paper that is complete but not yet polished. In that sense, it must possess an introduction, a body, and a conclusion, which is to say, the topic must be already identified, its main thesis stated, and the bibliographical support identified and studied. Writing a rough draft allows one to write a structured text that is supposed to be revised and edited later in order to arrive at the final version which is to be submitted for evaluation.
