Correct Answer - C
Osteoporsis is caused by decreased level of oestrogen. Oestrogen deficiency causes both the early and late forms of osteoporosis in past-menopausal women.
Osteoporosis is thinning or weaking of bones which makes them fragile and more likely to break. Women have low oestrogen level when they are transitioning through menopause. Hence, option(c) is correct.
