The primary satellite launching facility of ISRO is -

The correct answer is Option (1) → Sriharikota, Andhra Pradesh

ISRO’s main launch centre is the Satish Dhawan Space Centre (SHAR), Sriharikota, on an island off the coast of Andhra Pradesh. All its satellite launch vehicles (PSLV, GSLV, LVM3) lift off from here. The site lies on the east coast, close to the equator, so rockets launched eastwards over the sea gain from the Earth’s rotation and spent stages fall into the Bay of Bengal.
