Answer:

D) parathyroid hormone

Explanation:

Calcitonin and parathyroid hormones work against each other. Calcitonin is secreted by thyroid gland and parathyroid hormone is secreted by parathyroid gland. They both regulate serum calcium levels by affecting kidney, bone and intestine.

Calcitonin decreases calcium level when it has crossed its normal level. It is produced by parafollicular cells of the thyroid gland. Parathyroid hormone increases calcium level. It increases blood calcium level by simulating osteoclasts which release calcium from bone.
