Question

Assertion (A): In a normal standing posture, both knees touch each other, while there is a gap of 3-4 inches between the ankles.

Reason (R): It is due to Genu Valgum and it can develop due to an injury or infection in the knee or leg, rickets, severe lack of lack of  vitamin D and calcium, obesity, or arthritis in the knee.

In the context of the above two statements, which one of the following options is correct?

पर्याय

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

• Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A). 

• Assertion (A) is true, but Reason (R) is false.

• Assertion (A) is false, but Reason (R) is true.

Answer 1

Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).

Explanation:

1. The knees should touch each other while standing, according to (A). There should be 3–4 inches of space between the legs. This talks about a disease called Genu Valgum, which means "knock-knees."
2. Reason (R) is right when it says that Genu Valgum can be caused by things like infections, accidents, rickets (not getting enough vitamin D), osteoporosis, being overweight, or arthritis.
3. But the reason doesn't exactly explain the anatomical fact that is being talked about (why the knees touch but the ankles stay apart).
