The correct answer is C. Bone resorption inhibitor
Step-by-step explanation:
Osteoporosis is a disease caused by excessive bone resorption, this means the body absorbs and breaks down part of the bone, and this leads to brittle bones. This phenomenon is common after menopause because due to estrogen deficiency bone resorption increases. Despite this, osteoporosis can be effectively treated through bone resorption inhibitor that decreases or inhibits bone resorption and therefore helps the bone to restore over time. According to this, if a doctor suspects a patient is suffering from osteoporosis post-menopause the best drug to treat her is "bone resorption inhibitor".
