What condition is caused by Vitamin D deficiency in adults?

  1. osteomalacia

  2. Rickets

  3. Beriberi

  4. Pellagra

The correct answer is: osteomalacia

Osteomalacia is the correct answer as it is a bone disorder caused by a deficiency in Vitamin D. Vitamin D helps with the absorption of calcium and phosphorus, important nutrients for bone health. Without enough Vitamin D, bones become soft and weak, making them more prone to fractures. Rickets, on the other hand, is a similar bone disorder but it specifically affects children and is caused by a vitamin D and calcium deficiency. Beriberi and pellagra are both caused by deficiencies in other nutrients, specifically thiamine and niacin respectively, and do not involve Vitamin D.
