The correct answer is if a student forms a study group you get better grades.

Explanation:

All the options presented in the question use the zero conditional structure, used to express conditions and results in present, things that are generally true under specific circumstances. It is divided in two clauses: the first one indicated with if or when and the result after it. Both clauses use simple present. The first option is correct because the subjects and the verb forms agree in both parts ("a student forms" and "you get.")
