C	Either A or B
D	None of the above

Explanation:

Detailed explanation-1: -ACTH activates the adrenal glands to release cortisol, which induces metabolic effects. Cortisol also acts back on the hypothalamus and pituitary gland by negative feedback.

Detailed explanation-2: -Another example of negative feedback is the regulation of the blood calcium level. The parathyroid glands secrete parathyroid hormone, which regulates the level of calcium in the blood. If calcium decreases, the parathyroid glands sense the decrease and secrete more parathyroid hormone.

Detailed explanation-3: -Positive and negative feedback mechanisms are two different types of feedback mechanisms. Positive feedback stimulates and increases hormone secretion. Negative feedback stops and inhibits the hormone from being produced.
