The correct answer is a.
With advanced age, the ability of osteoblasts to divide and to lay down osteoid is reduced, giving rise to senile osteoporosis. In CONTRAST, postmenopausal osteoporosis is characterized by hormone-dependent acceleration of bone loss. Note that in the vignette, the patient is MALE, and therefore, subjected to the senile version of osteoporosis
