Atal Innovation Mission is set up under the

1. A

   Department of Science and Technology

   (a) Department of Science and Technology. DST runs other innovation schemes, but Atal Innovation Mission is not housed there, so DST is not the key.

2. B

   Ministry of Labour and Employment

   (b) Ministry of Labour and Employment. Labour ministry does not host AIM, so this is not the key.

3. C

   NITI Aayog

   (c) NITI Aayog. Atal Innovation Mission (Atal Tinkering Labs, Atal Incubation Centres) is a flagship of NITI Aayog. That parent body is the official key.

4. D

   Ministry of Skill Development and Entrepreneurship

   (d) Ministry of Skill Development and Entrepreneurship. Skill India is a different architecture; AIM is not under MSDE, so this is not the key.

Summary. Official key is (c) NITI Aayog. AIM was set up under NITI to promote a culture of innovation and entrepreneurship through tinkering labs and incubators. DST, labour and skill ministries run neighbouring programmes, not this mission. Honour the stored letter (c).
