  1. 1380 Kg in mass.

  2. Cuboidal in shape

  3. Fuel and oxidiser were stored in two tanks of 390 litres each.

  4. all of the above

Show answer
Correct Option: D
Explanation:

The mass of Chandrayaan was 1380 kg at launch, 675 kg at lunar orbit and 523 kg after releasing the impactor. It was cuboidal in shape. The spacecraft used a bipropellant  integrating propulsion system to reach lunar orbit as well as its maintenance while operating the moon. The power plant consisted of one 440 N engine and eight 220 thrusters. Fuel and oxidiser were stored in two tanks of 390 litres each.

The Chandrayaan used a _______________ integrated propulsion system to reach lunar orbit as well as orbit and altitude maintenance while orbiting the Moon.
