Final Answer :
D
Explanation :
Parathyroid hormone is released when blood calcium ion concentration declines. It acts to stimulate the release of calcium from bones, increase calcium reabsorption in the kidneys, and enhance calcium absorption in the intestines to raise blood calcium levels. The other choices are not related to regulation of blood calcium levels.
