The correct answer is "results from the heat produced when muscles contract."

Here's why:

1. "Body temperature will increase after blood vessels in the skin constrict." - This is incorrect. When blood vessels in the skin constrict, it actually helps to conserve body heat, not increase body temperature.

2. "Body temperature decreases when the rate of the chemical reactions increase." - This is also incorrect. The rate of chemical reactions in the body, also known as metabolism, generates heat. Therefore, an increase in the rate of chemical reactions would likely increase body temperature, not decrease it.

3. "Body temperature is lowered by shivering." - This is incorrect. Shivering is a mechanism the body uses to generate heat and increase body temperature, not lower it.

4. "Body temperature results from the heat produced when muscles contract." - This is correct. When muscles contract, they generate heat, which contributes to body temperature.

5. "Body temperature is raised by sweating." - This is incorrect. Sweating is a mechanism the body uses to cool down and lower body temperature, not raise it.
