B. 65 percent

C. 75 percent

D. 85 percent

i think its D

The answer is D

yes it is , thanks .

To the people that said 55 ,thats not funny we really needed help with our work

To determine the correct answer, we need to understand the source of body heat and the role of muscle contractions in heat production.

The human body generates heat through various metabolic processes, including muscle contractions. When muscles contract, they require energy in the form of adenosine triphosphate (ATP), which is produced through cellular respiration. As a byproduct of this process, heat is released.

According to scientific research, approximately 85 percent of the heat produced in the body is the result of muscle contractions. Therefore, the correct answer is option D, 85 percent.
