In what context did Einstein meet Mileva Maric?

Correct answer: She was his classmate at Zurich Polytechnic

The governing concept is connecting a significant personal relationship with its biographical setting. Einstein met Mileva Maric while both were students at Zurich Polytechnic, where they shared an academic environment and interests in scientific study. Thus option A is correct. The detail is important because Mileva belonged to the period of Einstein's higher education and later became connected with his personal life. Option B invents a position at the Munich school and confuses her with an authority figure. Option C is impossible in the lesson's context: the patent office was Einstein's workplace, not Mileva's business. Option D combines an unrelated place and occupation. The correct answer is identified by linking Mileva with Zurich Polytechnic and Einstein's student years.
