Where did Mileva Maric meet Einstein?

Correct answer: At Zurich Polytechnic

The governing concept is locating the meeting that became important in Einstein’s personal and academic life. Mileva Maric met Einstein at Zurich Polytechnic, where both were students and classmates. Therefore option C is correct. Princeton was associated with Einstein much later, while the Munich school belonged to an earlier stage of his education. The Swiss Patent Office was his workplace in Bern after his studies, so it was not the place where he first met Mileva. Distinguishing the educational institution from the later workplace prevents confusion between two important locations in the biography. The answer is based on their shared student life at Zurich Polytechnic.
