Which Geosynchronous Satellite Launch Vehicle was used by ISRO to launch Chandrayaan – 2 space craft?

The correct answer is A) GSLV Mk III-M1. Chandrayaan-2 lifted off from Sriharikota on 22 July 2019 on this vehicle. The launcher has since been renamed LVM3 (Launch Vehicle Mark-3), so you may see that name in newer sources.

Why the others fail:

• B) GSLV Mk II-M2 is the two-stage variant with the indigenous cryogenic upper stage. Its lift capacity to GTO is about 2 tonnes, too little for a spacecraft of roughly 3.8 tonnes.
• C) GSLV Mk IV and D) GSLV Mk V are not operational ISRO launch vehicles. Only the Mk II and Mk III variants of GSLV have flown.

The core concept is the GSLV family and the payload-to-vehicle matching. Mk III was built for heavier satellites, and this is why it was chosen for Chandrayaan-2, a point that also links to ISRO's rise in heavy-lift capability for Mains answers on space technology.

Trap: aspirants pick the Mk II because it is the more familiar GSLV. Always check the payload mass against the vehicle's GTO capacity.
