Answer 1

parathyroid

Step-by-step explanation:

Answer 2

The right answer is A.

Parathyroid hormone, also known as parathyroid hormone, is a hypercalcemic and hypophosphatemic peptide hormone secreted by the parathyroid glands.

It is rather correct to say that PTH (parathyroid hormone) increases kidney production of active vitamin D because it is where vitamin D is synthesized and not in the intestine.
