Extrinsic motivation is defined as motivation by external factors or rewards.

• A. Motivation by external factors or rewards
• B. Motivation by intrinsic interest
• C. Motivation by personal growth
• D. Motivation by curiosity

Answer: (A)

Extrinsic motivation means doing something for rewards or external pressures rather than for personal enjoyment. So this definition fits motivation by external factors or rewards—praise, grades, money, prizes, or avoiding punishment drive the behavior rather than an inner interest in the activity itself. The other options point to internal drives: intrinsic interest is doing it for the love or enjoyment of the activity, personal growth is about self-improvement from within, and curiosity is about a wish to learn something new. In music, extrinsic motivators can prompt practice or performance, but lasting engagement usually comes from internal enjoyment and meaning.
