What advanced technology is being tested in ISRO’s new “Next Generation Launch Vehicle” (NGLV) project to replace the GSLV?

Correct option is A

The correct answer is (a) Reusable booster stage with semi-cryogenic engine
Explanation:

• ISRO’s Next Generation Launch Vehicle (NGLV) project includes the development of a semi-cryogenic engine (using LOX and kerosene or methane) for the core and booster stages, replacing existing liquid stages like L110.

• The design also features partial reusability, especially for the first stage and boosters, to reduce launch costs and improve turnaround.
Information Booster:

• NGLV is envisioned as a three-stage vehicle with semi-cryogenic propulsion in the lower stages and a cryogenic upper stage.

• ISRO is developing reusable booster and first-stage technology, including vertical takeoff and vertical landing (VTVL) capabilities.

• The SCE-200 (SE-2000) engine, a high-thrust semi-cryogenic engine using LOX/RP-1 with an oxi
