question

thyroxine

i dont know yet

Explanation:

When blood - calcium levels drop, parathyroid hormone is released. It acts on bones, kidneys, and the intestine to increase blood - calcium levels. Calcitonin lowers blood - calcium levels when they are too high. Thyroxine is related to metabolism, and estrogen is a sex hormone not directly involved in calcium homeostasis in this context.

Answer:

B. Parathyroid hormone
