Which musical instrument did Einstein develop interest in during childhood?

Correct answer: Violin

The governing concept is recalling the cultural and personal interests included in a biography. Einstein developed a strong interest in music and learned to play the violin, so option A is correct. This detail is important because it shows that his personality was not limited to scientific study; music also became a source of enjoyment and emotional balance. Tabla, sitar, and flute are all genuine musical instruments, but none is the instrument connected with Einstein in this chapter. They function as plausible distractors because they are familiar instruments, especially in an Indian school context. The answer should be remembered as Einstein’s love of the violin alongside his interest in mathematics and physics.
