• B. 2 & 3
• C. 1 & 2
• D. All are correct

Answer 1

Answer:

A. 1 & 3

• Correct Answer : Option A) 1 & 3

• The GSLV Mk III (Geosynchronous Satellite Launch Vehicle Mark III), also known as LVM3 (Launch Vehicle Mark 3), is an important launch vehicle developed by the Indian Space Research Organisation (ISRO).

• It is India's heaviest and shortest rocket - True

• The GSLV Mk III is indeed India's heaviest launch vehicle with a lift-off mass of approximately 640 tonnes. Despite its heavy payload capacity, it has a relatively compact design, making it the shortest among India's operational orbital-class rockets at about 43.4 meters.

• It uses a two-stage propulsion system - False

• The GSLV Mk III employs a three-stage propulsion system, not two stages:

• First stage: Two S200 solid rocket boosters

• Second stage: L110 liquid stage (with two Vikas engines)

• Third stage: C25 cryogenic upper stage (with CE-20 engine)

• It can place 8 tonnes in Low Earth Orbit - True

• The GSLV Mk III has a payload capacity of approximately 8 tonnes to Low Earth Orbit (LEO) and about 4 tonnes to Geosynchronous Transfer Orbit (GTO), making it India's most powerful launch vehicle.
