Given below are two statements, one is labelled asAssertion (A) :and other as Reason (R):Assertion (A):Invert sugar is sweeter than sucrose.Reason (R):Invert sugar is obtained by the hydrolysis of sucrose.Select the correct answer from the codes given below.

1. A

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

   Both limbs are true, but hydrolysis is how invert sugar is made, not the reason it tastes sweeter. The sweetness jump comes from free fructose (and glucose) after inversion, so (R) is not the correct explanation of (A).

2. B

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

   Both (A) and (R) are true, but (R) is not the correct explanation of (A). Invert sugar is a glucose–fructose mix from sucrose hydrolysis; it is sweeter mainly because fructose is sweeter than sucrose. That is the official key.

3. C

   (A) is true but (R) is false

   (A) is true; calling (R) false would deny the standard inversion reaction: sucrose + water → glucose + fructose.

4. D

   (A) is false but (R) is true

   (A) is not false: invert sugar is sweeter than table sucrose on equal-weight tasting.

Summary. Official key is (b). Inversion of sucrose yields invert sugar; that process is true but does not by itself explain greater sweetness. Fructose’s higher sweetness does. Honour the stored letter (b).
