Final Answer :
B
Explanation :
Parathyroid hormone (PTH) secretion decreases when blood calcium levels increase, as PTH's primary role is to increase blood calcium levels by stimulating the release of calcium from bones, increasing calcium absorption in the intestines, and reducing calcium excretion in the kidneys.
