Consider the following statements regarding Cryogenic Rockets:

1. The cryogenic stage is a very complex system due its use of propellants at extremely high temperatures.

2. The propellants used by cryogenic system are liquid oxygen and liquid hydrogen.

Which of the statement(s) given above is/are correct?

1 only

2 only

Both 1 and 2

Neither 1 nor 2

2 only

The cryogenic stage is technically a very complex system due to its use of propellants at extremely low temperatures and the associated thermal and structural problems.
It uses liquid fuels (Oxygen liquifies at -183 deg C and Hydrogen at -253 deg C) that are cooled to very low temperatures.
Cryogenic propellants are liquefied gases stored at very low temperatures, most frequently liquid hydrogen (LH2) as the fuel and liquid oxygen (LO2 or LOX) as the oxidizer.
