Answer:
c. accidental removal of the parathyroid glands during surgery
Explanation:
Parathyroid gland is found closely situated at the back of the thyroid gland in the human neck region. Regulation of serum calcium levels in the body is a major function of the parathyroid gland through the secretion of a hormone called parathyroid hormone or parathormone.
During the surgery conducted to remove the thyroid gland, it is very likely that the parathyroid glands were accidentally damaged or removed. This most likely led to the non--secretion of parathormone, which is responsible for secretion of calcium in the body, when calcium levels drop.
