C.  Due to calcitonin is destroyed in the GI tract before performing its function.

Explanation:

Calcitonin is a hormone that is released by the parafollicular cells or c- cells of the thyroid gland in humans. Calcitonin performs the regulation of the calcium level in blood which is the opposite action of parathyroid hormone. It reduces the effect of osteoclasts. So. if the calcitonin level decreases it will lead to the more calcium in the blood and cause hypercalcemia.

Hypercalcemia has various symptoms such as pain in the bones  or abdomen, dehydration, excess urination, fatigue, loss of appetite or thirst , constipation nausea , mental confusion, muscle weakness, or weight loss.

Due to the polypeptide nature of calcitonin hormone, calcitonin is destroyed in the GI tract if you ingest pill of calcitonin so therefore, it administered by injection or nasal spray.
