	a.	She may have a calcitonin-secreting tumor of the thyroid gland.
	b.	Further tests will likely show that plasma level of calcitriol is high.
	c.	She should be examined for a possible tumor of the parathyroid gland.
	d.	Osteoclast activity is abnormally high relative to osteoblast activity.

Answer 1

D. Osteoclast activity is abnormally high relative to osteoblast activity.

As they already mentioned tha the bone density is normal and there is no fracture so it is indicating that the osteoclast activity is normal which is a process of break down of old bone tissue. all other option are correct they having roles in regulating calcium level.
