Q. Which one of the following is the primary difference between Geosynchronous Satellite Launch Vehicle (GSLV) and Polar Satellite Launch Vehicle (PSLV) in terms of capability?

[A] GSLV is used for Earth observation missions, while PSLV is used for interplanetary missions.

[B] GSLV can carry heavier payloads to GTO, while PSLV is designed for LEO and polar orbits.

[C] GSLV is reusable, while PSLV is not.

[D] GSLV uses only solid fuels, while PSLV uses a combination of liquid and solid fuels.

Answer: B
Notes:

Explanation – GSLV is designed for heavier payloads and is capable of reaching Geosynchronous Transfer Orbit (GTO), which is crucial for launching communication satellites and other high-orbit missions. On the other hand, PSLV is more suited for lighter payloads, primarily targeting Low Earth Orbit (LEO) and polar orbits, making it ideal for Earth observation and interplanetary missions.
