Given below are two statements, one is labelled asAssertion (A) :and other as Reason (R):Assertion (A):Ahmedabad is the largest centre of cotton textile industry in India.Reason (R):Ahmedabad is located in Major cotton growing region of India, so it has no problem of raw materials.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)

   (a) Both true and R explains A. Ahmedabad is a major mill town but not India’s largest cotton-textile centre, so A is not true and this pair fails.

2. B

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

   (b) Both true but R does not explain A. A is false, so ‘both true’ cannot hold.

3. C

   (A) is true but (R) is false

   (c) A true, R false. A is false: Mumbai historically, and a wider western-southern belt today, outrank Ahmedabad as the single ‘largest’ centre. R is not false.

4. D

   (A) is false but (R) is true

   (d) A false, R true. Ahmedabad is not the largest cotton-textile centre in India, so A is false. It does sit in Gujarat’s great cotton belt and is not starved of raw cotton, so R is true. That combination is the official key.

Summary. Official key is (d). Assertion A is false because Ahmedabad is not India’s largest cotton-textile centre. Reason R is true because the city lies in a major cotton-growing region and raw-material access is not the binding constraint.
