Explanation:

In human anatomy (a subfield of Biology, which is part of Natural Science), skeletal muscles alone typically make up about 30 - 40% of a person's body mass, and when considering all muscle types (including smooth and cardiac muscles), muscles generally make up more than 40%? Wait, no, correction: The average muscle mass percentage in the human body (for an adult) is around 40 - 50% of total body mass. So among the options, 40% (option C) is the correct choice as muscles make up more than 40%? Wait, actually, the typical muscle mass for a healthy adult is about 40% of body weight (for men, maybe a bit more, women a bit less, but the options here: 10% is too low, 25% too low, 40% is the threshold where muscles are more than that (since average is around 40 - 50), and 75% is too high (as fat, bones, organs are also there). So the correct answer is C.

Answer:

C. 40%
