The correct answer is C. Adrenal gland.
Cortisol is a steroid hormone that is produced by the adrenal glands. It is released in response to stress and helps the body to respond to a variety of challenges. Cortisol helps to regulate blood sugar levels, blood pressure, and immune function. It also helps to break down fat and muscle tissue for energy.
The thyroid gland is a butterfly-shaped gland located in the neck. It produces hormones that regulate metabolism, growth, and development. The pituitary gland is a pea-sized gland located at the base of the brain. It produces hormones that control a variety of body functions, including growth, reproduction, and metabolism. The parathyroid glands are four small glands that are located on the back of the thyroid gland. They produce hormones that regulate calcium levels in the blood.
Cortisol is not produced by the thyroid gland, pituitary gland, or parathyroid gland. It is produced by the adrenal glands.
