d. None of the above

a. helps regulate body temperature

Explanation:

The "Integumentary System" of the human body is the "Skin," which is considered the largest organ. It consists of the following functions: Protection, Sensory, Thermoregulation and Vitamin D Synthesis.

Under "Thermoregulation," the skin helps regulate the body's temperature. For example, when a person exercises, the skin becomes red. This is because the arterioles have to dilate in order for heat to escape from the body. It is also coupled with "sweating." This helps the body lower its temperature. This makes choice a correct.

Choice b and choice c are functions of the skeletal system. It helps the body move and it also stores mineral within the bones.
