Question

Assertion (A): Vitamin D cannot be stored in our body. Reason (R): Vitamin D is fat-soluble vitamin and is not excreted from the body in urine.

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

Hint:

It’s important to remember the distinction between fat-soluble and water-soluble vitamins. Fat-soluble vitamins like Vitamin D, A, E, and K are stored in the liver and fatty tissues, while water-soluble vitamins are not stored in the body and are usually excreted through urine when in excess.

Answer 1

The Correct Option is C

Vitamin D, classified as a fat-soluble vitamin, behaves differently from water-soluble vitamins such as vitamin C and the B vitamins. The primary characteristic of fat-soluble vitamins is their ability to be stored in the body's fatty tissues and liver. This means that when you consume vitamin D, it is absorbed through the intestines, transported via the bloodstream, and then stored in the fat cells and liver for later use. This characteristic makes Assertion (A) true, as it correctly states that Vitamin D is a fat-soluble vitamin. \bigskip The confusion arises with Reason (R), which incorrectly states that Vitamin D is excreted from the body in urine. This is not accurate for fat-soluble vitamins. Unlike water-soluble vitamins, which are excreted through urine when in excess, fat-soluble vitamins like Vitamin D are stored in the body. They do not get excreted through the urinary system; instead, they remain in fat and liver tissues for future utilization. This makes Reason (R) false. \bigskip Step 2: Thus, based on the explanation above, the correct answer is option (3). \bigskip
