The answer is letter
B.
Body composition
directly affects flexibility because of the structure of the joints, ligaments,
tendons, muscles, fat, and skin that are traits inherited from a person’s set
of parents. Generally women are more flexible than men because of their higher
fat concentrations and mainly because of their ability to experience pregnancy
where bones expand and relax to give way for the baby. Other factors that affect
flexibility are body temperature, activity level, and age. Some people are
naturally-born flexible but through the right amount of practice it can also be
achieved.
