Which option best proves independent thinking in Einstein's biography?

Correct answer: Dissatisfaction with rote learning and desire to understand

The governing concept is independent thinking: a person does not accept a method merely because authority supports it, but asks questions and seeks understanding. In the biography, young Einstein felt dissatisfied with mechanical, rote-based schooling and preferred learning through curiosity, reasoning, and direct engagement with ideas. Therefore, option A is correct because it connects a clearly described attitude with the quality being tested. Option B represents obedience without thought, not independence. Option C is unrelated to his intellectual development, while option D gives an unsupported motive for his violin playing. The question therefore asks readers to infer a character trait from a biographical incident, not simply recall an isolated fact.
