India's first completely solar-powered airport is:

Explanation

Cochin International Airport, also known as CIAL, is the answer because it became fully solar-powered in 2015 with a 12 MW solar plant. Press Information Bureau, Government of India, Ministry of Civil Aviation records the decisive point: Cochin International Airport in India became the world's first fully solar-powered airport in 2015. The importance of the fact is that CIAL was not merely using some solar power; it crossed the threshold of being fully solar-powered and generated more solar power than it consumed. That is why Bangalore KIA, Delhi IGI and Mumbai CSIA do not fit this specific first-in-India and first-in-the-world marker.

Why the other options are wrong

• (A) Bangalore KIA is wrong because Cochin International Airport, not Bangalore KIA, became fully solar-powered in 2015.
• (B) Delhi IGI is wrong because the first fully solar-powered airport claim is attached to Cochin International Airport, not Delhi IGI.
• (D) Mumbai CSIA is wrong because the 2015 fully solar-powered milestone belongs to Cochin International Airport.

Concept

This tests the Science and Technology theme of renewable-energy applications in transport infrastructure. It recurs in RAS because such questions connect clean-energy policy with practical Indian examples.
