Consider the following airports:1.Donyi Polo Airport2.Kushinagar International Airport3.Vijayawada International Airport In the recent past,which of the above have been constructed as Greenfield projects ?

1. A

   1 and 2 only

   1 and 2 only. Donyi Polo (Itanagar) and Kushinagar were greenfield. Vijayawada is a developed / brownfield international airport, not a new greenfield build.

2. B

   2 and 3 only

   2 and 3 only. Drops Donyi Polo; wrongly keeps Vijayawada.

3. C

   1 and 3 only

   1 and 3 only. Drops Kushinagar; keeps Vijayawada.

4. D

   1, 2 and 3

   All three. Vijayawada is not keyed as a recent greenfield.

Summary. Official key is (a) 1 and 2 only. Donyi Polo Airport (Itanagar) and Kushinagar International Airport were built as greenfield projects. Vijayawada (Gannavaram) is an upgraded existing airport, not a fresh greenfield in the same sense. So 3 drops.
