Einstein's association with Princeton in America shows which phase of his life?

Correct answer: Scholarly life after leaving Germany

The correct answer is D. Einstein’s association with Princeton represents the later scholarly phase of his life, after he had left Germany and established himself in the United States. Princeton is therefore a chronological clue: it belongs neither to his birth, childhood, nor to his early schooling in Munich. In a biographical account, places help readers follow the stages of a person’s life. The question uses Princeton to identify Einstein as an internationally respected scholar living and working after the upheavals that forced him away from Germany. Option D is precise because it combines the important sequence, leaving Germany first and pursuing scholarly life in America afterward.
