please select the best answer from the choices provided.
a
b
c

Explanation:

• Option A is incorrect because stiff muscles don't only come from overwork; inactivity can also cause them.
• Option B is incorrect as stiff muscles aren't solely due to inactivity; overworking muscles can also lead to stiffness.
• Option C is correct because overworking (like excessive exercise) or underworking (prolonged inactivity) muscles can both result in muscle stiffness.

C. Stiff muscles result from both over- and underworking them.
