Edvaya · Accepted Answer

The correct answer is Assertion (A) is false, but Reason (R) is true.. **A is FALSE:** Vitamin D is a **fat-soluble vitamin**. Being fat-soluble, it **can** be stored in adipose tissue and liver in the body for long periods. It is NOT excreted readily in urine. Therefore, the assertion that "it cannot be stored" is incorrect. **R is TRUE:** Vitamin D is indeed fat-soluble and is not excreted through urine (unlike water-soluble vitamins like Vitamin C and B-complex). **Answer: (D) — A is false, R is true.** *Note: Fat-soluble vitamins (A, D, E, K) are stored in body fat/liver. Water-soluble vitamins (B, C) cannot be stored and are excreted in urine.*
