Explanation:

Here’s the thing: Chandrayaan-1, India’s first lunar mission, took off from Sriharikota. Let’s break down the choices:

- Srikalahasti—This is a temple town in Andhra Pradesh. Famous for the Srikalahasteeswara temple, not for space launches.

- Srikakulam—That’s a district way up north in Andhra Pradesh. Known for its beaches, not spaceports.

- Sriharikota— This is ISRO’s launch site. The Satish Dhawan Space Centre is here, and almost all Indian rockets lift off from here. No arguing—this is the answer.

- Srisailam—Wildlife sanctuaries, temples, the big dam on River Krishna. No history of rocket launches.
