Given below are two statements, one is labelled asAssertion (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.

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

Correct answer: (d) (A) is false, but (R) is true.

Explanation

  1. A

    Both (A) and (R) are true and (R) is the correct explanation of (A).

    Claims that both Assertion (A) and Reason (R) are true and (R) correctly explains (A). This option is incorrect because the human body does not synthesise all required vitamins on its own, rendering the assertion factually false.

  2. B

    Both (A) and (R) are true, but (R) is not the correct explanation of (A).

    Claims that both (A) and (R) are true, but (R) is not the correct explanation of (A). This is incorrect as the primary premise regarding the human body synthesising all vitamins is factually wrong, making the assertion completely incorrect.

  3. C

    (A) is true, but (R) is false.

    Claims that Assertion (A) is true, but Reason (R) is false. This is incorrect because the human body cannot synthesise all essential vitamins, meaning the assertion is false and the reason stating vitamins are essential for growth is actually true.

  4. D

    (A) is false, but (R) is true.

    is (d) because Assertion (A) is completely false since the human body cannot synthesise all the vitamins it requires and must obtain many of them through diet, whereas Reason (R) is completely true as vitamins are indeed essential organic compounds necessary for the proper growth, development, and metabolic functioning of the human body.

Summary. Official key is (d) as the human body does not synthesise all the vitamins it needs, meaning Assertion (A) is false. However, Reason (R) is true because vitamins are undeniably essential for the proper growth and functioning of the body. Many vital vitamins like Vitamin D and certain B vitamins are either synthesised in limited amounts or must be obtained directly from dietary sources. Therefore, statement (A) is incorrect while statement (R) is entirely correct.
