Q117 (UPPCS/2021) Science & Technology › Basic Science (Physics, Chemistry, Biology)

Given below are two statements, one is labelled as Assertion (A) and other as Reason (R) :
Assertion (A) : Human body synthesises all the vitamins required by it.
Reason (R) : Vitamins are essential for proper growth of the body.
Select the correct answer using the codes given below.
Codes :

Explanation

The Assertion (A) is false because the human body cannot synthesize most of the vitamins it requires. Vitamins are essential organic micronutrients that must generally be obtained through diet. While the body can synthesize some vitamins under specific conditions—such as Vitamin D through exposure to sunlight and Vitamin K or certain B vitamins by gut flora—it cannot produce the full spectrum (like Vitamin C or Vitamin A) required for survival.

The Reason (R) is true because vitamins are indeed vital for various physiological functions, including metabolic processes, immune system maintenance, and proper growth of the body. Since the assertion is factually incorrect but the reason is a correct statement about the nature of vitamins, the correct answer is option D.
