Answer:
C. a stretched rubber band
Step-by-step explanation:
A. A wind toy is unwounded so, it cannot have elastic potential energy. Hence, it’s a wrong answer
B. When a basket is placed on ground, it is in steady state. So, it cannot have any kind of energy. Hence, it’s also wrong answer.
C. Stretched rubber band has elastic potential energy because it will do work when it will be released. So, it’s a right answer.
D. It’s wrong answer because “C” is right answer.
Hence, “C” is the correct answer.
