When you hold something heavy in your arms and then put it down, your muscles slowly return to a normal condition because of a. elasticity. b. torque. c. tension. d. mechanics.

C. tension.

Explanation:

Muscle elasticity is the ability of muscles to distend and regain their initial length after contraction.

When you hold something in your arms and bend down to place it on you, you contract your muscles because of the force used to carry and deposit the object on the floor. When you lift, your muscles regain their initial length because of elasticity. That is, the elasticity is related to the action in which your muscle is contracted or stretched, but back in place.
