Correct Answer: C
Solution :
[c] It is the first operational launch vehicle of ISRO. PSLV is capable of launching 1600 kg satellites in 620 km sun -synchronous polar orbit and 1050 kg satellite in geo-synchronous transfer orbit. PSLV has four stages using solid and liquid propulsion systems alternately. The first stage is one of the largest solid propellant boosters in the world and carries 139 tonnes of propellant. ISRO has envisaged a number of variants of PSLV to cater to different mission requirements. There are currently three operational versions of the PSLV-the standard (PSLV), the core-alone (PSLV-CA) without the six strap-on booster motors, and the (PSLV-XL) version, which carries more solid fuel in its strap-on motors than the standard version. So far, PSLV has launched 87 satellites.
