- DThyroxine
Explanation
The correct answer is C. Parathyroid hormone, also known as parathormone, is secreted by the parathyroid glands. Its primary function is to maintain homeostatic levels of calcium and phosphate in the blood. When blood calcium levels are low, this hormone stimulates the release of calcium from bones into the bloodstream and reduces calcium excretion by the kidneys. Simultaneously, it regulates phosphate levels by increasing its excretion through urine. Glucagon manages blood sugar, growth hormone controls physical development, and thyroxine regulates metabolism.
