To which city did Einstein go for higher studies?

Correct answer: Zurich

The correct answer is C, Zurich. Einstein went to Zurich for higher studies and joined the Polytechnic there, where he continued his scientific education. The distinction among the cities is important: Munich was associated with his earlier schooling, while Bern became significant later because he worked at the Swiss Patent Office there. Berlin was another important city in his life, but it was not the city named for this stage of higher education. The governing idea is chronological identification—Zurich belongs to his student years, whereas Bern belongs to his employment after graduation. Therefore option C is the precise answer.
