BMD Test is performed for

Arthritis
Osteoporosis
Osteomalacia
None of these

The correct answer is (b).

BMD stands for Bone Mineral Density. It is a test that measures the amount of bone mineral in a specific area of the body, usually the hip or spine. BMD is used to diagnose and monitor osteoporosis, a condition in which the bones become weak and brittle.

Arthritis is a condition that affects the joints. It is not caused by a lack of bone mineral density.

Osteomalacia is a condition in which the bones become soft and weak. It is caused by a lack of vitamin D or calcium.

Therefore, the correct answer is (b).
