With reference to the NTPC unit at Singrauli, which of the following statements is/are correct?1.It is situated in the northern part of Chhattisgarh State.2.It is NTPC's oldest unit.Select the correct answer using the codes given below.

1. A

   Only 1

   Only 1 is wrong because the NTPC unit at Singrauli is not in the northern part of Chhattisgarh. Singrauli Super Thermal Power Station stands at Shaktinagar in Uttar Pradesh, on the Singrauli coal belt that also touches Madhya Pradesh. Statement 1 is therefore false.

2. B

   Only 2

   Only 2 is the official key. NTPC’s Singrauli station is its oldest commercial thermal unit, the first to go on stream in the Corporation’s thermal fleet. Statement 1 misplaces it in Chhattisgarh. Hence only 2 is correct.

3. C

   Both 1 and 2

   Both 1 and 2 cannot be right because statement 1 is geographically false. Korba and other plants lie in Chhattisgarh; Singrauli does not. This option is not the key.

4. D

   Neither 1 nor 2

   Neither 1 nor 2 would deny the true claim that Singrauli is NTPC’s oldest unit. This option is therefore wrong.

Summary. Official key is (b) Only 2. Singrauli STPS is in Uttar Pradesh, not in northern Chhattisgarh. It is NTPC’s oldest thermal power station. Statement 1 confuses the Singrauli coal region with Chhattisgarh plant locations. Statement 2 is accepted as correct. Only (b) is the keyed code.
