Answer 1

Its C

Step-by-step explanation:

Answer 2

Let us evaluate the given answers.

A.
Because the wind-up toy has been unwound, it has no stored elastic potential energy.
This is not a correct answer.

B.
A basketball on the ground is in equilibrium. It has no stored elastic energy.
This not a correct answer.

C.
A stretched rubber band is not in equilibrium. It has stored elastic energy that will do work (propel the rubber band) when it is released.
This is a correct answer

D.
This is not a correct answer because only C is correct.
