During the resting heart, that is, the number of times the heart beats per minute while the body is relaxed and at rest does not change significantly with age; But with age, there are changes in the ability of the heart to increase its rate during exercise and other moments of stress. Younger hearts usually usually speed up more faster than older ones when challenged. The maximum heart rate, the highest heart rate one can achieve as measured by a cardiac stress test declines gradually in adults as they age. The cause of this is slowing down of the heart's pacemaker cells.

A) is the correct answer:)
Answer:
Hypertrophy
Explanation:
Hypertrophy is an enlargement in our organ tissue that is caused by an increase in the size of its cells.
When we engage in bodyweight or weight exercise, our muscle fiber will experience some sort of damage/trauma. This will trigger a response within our body in order to fix that damage by releasing growth factor, cortisol, and testosterone. During this process, satellite cells will multiply and migrate tot he damaged muscle tissue. This is what caused an increase in size.
