Answer:

A. It is responsible for keeping the back and legs straight when you’re relaxed.

Explanation:

Muscle tone refers to the state of partial contraction of muscles when the individuals are not moving. Motor neurons command some of the muscle fibers to contract unconsciously. Muscle tone serves to keep the muscles ready for movement and keep the back and legs straight during the relaxed conditions. Muscle tone serves to reduce with age. Exercising improves the muscle tone and prevents their limping.
