What is the similarity between self-control and muscular strength? Both remain tireless upon excessive use. Both are replenished with rest. Both are stronger after exertion?

The right option is; both are replenished with rest.

Self-control is the ability to bring one's thoughts, emotions and behaviors under control when confronting temptations and compulsions. Excessive use of self-control can result in depletion and like muscular strength, it can also be replenished with rest.

Muscular strength is the amount of force that can be created by a muscle in one maximal effort. Certain factors such as age, gender, and heritable physical traits determine the amount of muscle strength that can be achieved.
