Not to worry buddy I will let you know about about GSLV-III or Geosynchronous Satellite Launch Vehicle Mark III of Indian Space Research Organisation so that you can check it easily.

The GSLV-III or Geosynchronous Satellite Launch Vehicle Mark III of Indian Space Research Organisation is a launch vehicle to launch satellites into geostationary orbit.

Description:-

Stage 1 – solid boosters
The GSLV-III uses S200 solid motors. Each booster has a diameter of 3.2 metres, a length of 25 metres, and carries 207 tonnes of propellant. These boosters burn for 130 seconds and produce a peak thrust of about 5,150 kilonewtons (525 tf) each

Stage 2 – liquid motor
The core stage, designated L110, is a 4-meter-diameter liquid-fueled stage carrying 110 tonnes of UDMH and N2O4. It is the first Indian liquid-engine cluster design, and uses two improved Vikas (rocket engine)s, each producing about 700 kilonewtons (70 tf)

Stage 3 – cryogenic upper stage
The cryogenic upper stage is designated the C25 and will be powered by the Indian-developed CE-20 engine burning LOX and LH2, producing 186 kilonewtons (19.0 tf) of thrust. The C-25 will be 4 metres (13 ft) in diameter and 13.5 metres (44 ft) long, and contain 27 tonnes of propellant.
