The best choice to complete the sentence is (Choice B) clarify.
The full sentence would read: "A recent study by a group of neurologists aims to clarify the long-term effects of concussions." This makes logical sense because the study is intended to understand and illuminate the effects, rather than to obscure, minimize, or exacerbate them.
