c

Explanation

Osteoporosis is caused by decreased level of oestrogen. It causes both the early and late forms of osteoporosis in post menopausal women. Osteporosis is thinning or weaking of bones which makes them fragile and more likely to break. Women have low estrogen level when they are transitioning through menophase. Hence, option (c ) is correct.
