Einstein's move to America was connected with what?

Correct answer: नाजी शासन से जर्मनी छोड़ना — Leaving Germany because of the Nazi regime

The correct answer is A because Einstein left Germany after the rise of the Nazi regime, which persecuted Jews and threatened intellectual freedom. His Jewish identity and opposition to Nazi policies made it unsafe for him to remain there. He eventually settled in the United States, where he continued his scientific work and also spoke strongly for peace and democracy. Option B is wrong because his violin playing was a personal interest, not the reason for migration. Option C is historically impossible, since this was a major political relocation, not a childhood trip. Option D is also incorrect: the Nobel Prize was awarded for his scientific work, but going to America was not a journey to receive it.
