Explanation:

Question 7

In human anatomy, the skeletal system (bones) typically accounts for about 20% of a person's body mass. 40% is too high, and 75% is far from the actual proportion.

Increasing flexibility helps address muscle imbalances by improving the range of motion and balance between muscle groups. Osteoporosis is a bone - related condition and flexibility exercises don't directly fix it. Low metabolism is related to factors like diet, activity level (but not flexibility in a direct - fixing way), and hormonal factors, and flexibility training doesn't fix low metabolism.

Answer:

C. 20 percent
