Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
The assertion is correct as old ladies are prone to osteoporosis. They have a lower bone density which leads to gradual loss of bone strength. Oestrogen maintains the calcium balance in the bones and blood. It helps in calcification of bones and also stimulates the hormones for greater absorption of calcium during tubular absorption. At the onset of menopause, the oestrogen level decreases which evokes a high risk of osteoporosis. The given reason is suitable for the assertion.
So, the correct answer is option A.
