Correct Answer: Option B
Explanation

The kidneys' primary function is osmoregulation, which is the process of regulating the balance of water and electrolytes in the body. The kidneys also produce urine, filter blood, and remove waste.

Vasoconstriction is narrowing or constriction of the blood vessels. It happens when smooth muscles in blood vessel walls tighten, which increases blood pressure.

The brain, liver, heart, skeletal muscles, and other organs produce heat in the body. The kidneys don't produce heat, but they do play a role in regulating body temperature. When the body is exposed to heat stress, the kidneys respond by redirecting blood flow to the skin to help the body lose heat. However, heat stress can also damage the kidneys.

Hormones are produced by endocrine glands, which are groups of cells located throughout the body. Yes, healthy kidneys produce hormones that help regulate many bodily functions, including blood pressure, bone health, and red blood cell production, but it's major function is osmoregulation - regulating the balancing of water and electrolytes in the body.
