With reference to coal- based thermal power plants in India, consider the following statements:1.None of them uses seawater.2.None of them is set up in water-stressed district.3.None of them is privately owned.How many of the above statements are correct?

1. A

   Only one

   Only one. All three ‘none of them’ claims are false.

2. B

   Only two

   Only two. Coastal plants use seawater; some sit in water-stressed districts; many are private.

3. C

   All three

   All three. Each blanket ‘none’ fails.

4. D

   None

   None. Mundra-type plants use seawater; several large plants are in water-stressed districts; NTPC is not the only owner — Adani, Tata and others run private plants.

Summary. Official key is (d) none. Indian coal plants include seawater-cooled coastal units, plants in water-stressed inland districts, and privately owned stations. Every ‘none of them’ sentence is wrong.
