d. Mark 5
ANSWER: Mark 3
Indian Space Research Organisation in a move to acquire heavier satellite launch capability has received a boost with the successful test of the cryogenic engine for the upper stage of the GSLV Mark 3 rocket. The test at the Mahendragiri ISRO Propulsion Research Centre lasted for around 640 seconds. Using Liquid Hydrogen at -253 degree C and Liquid Oxygen at -193 degree C as propellants, the CE20 or high thrust cryogenic engine developed at the Liquid Propulsion System centre has undergone 2 short duration tests for engine ignition and steady state performance. The first developmental flight of the GSLV Mark 3 will take place in December 2016. Mk3 is the biggest rocket made in India. It can launch satellites weighing 4 tonnes into geosynchronous orbit.
