Solution

The correct option is C

Parathormone


Parathormone, a hormone released by parathyroid glands, increases calcium level in the blood. Calcium plays a very important role in blood clotting. Therefore, deficiency of this hormone will decrease Ca2+ level in the blood, thus leading to a delay in blood clotting and increase in bleeding time.
