Answer : 2. "तमिलनाडु"
Explanation :

Prime Minister Modi inaugurated the Kulasekarapattinam Spaceport in Tamil Nadu, the second spaceport after the Satish Dhawan Space Centre. This facility will be used to commercially launch small satellite launch vehicles. The spaceport, spread over 2,350 acres, has 35 facilities including launch pads and rocket integration areas. The unique advantage of this spaceport is to launch directly south over the Indian Ocean, saving fuel for smaller rocket launches compared to the existing site.
