Answer 1

Correct option is (a) Reduces calcium ion reabsorption from digested food

To explain: PTH or parathyroid hormone is secreted by the parathyroid gland. It is important for regulating the blood calcium level along with thyrocalcitonin. PTH increases calcium ion absorption from digested food.
