TO ESCAPE FROM EARTH’S GRAVITY THE SPACE SHUTTLE USES LIQUID FUEL AND

A	OXYGEN
B	NITROGEN
C	SOLID ROCKET BOOSTERS
D	LIQUID ROCKET BOOSTER

Explanation:

Detailed explanation-1: -The Solid Rocket Boosters (SRBs) operate in parallel with the main engines for the first two minutes of flight to provide the additional thrust needed for the Orbiter to escape the gravitational pull of the Earth.

Detailed explanation-2: -The main engines burn liquid hydrogen–the second coldest liquid on Earth at minus 423 degrees Fahrenheit (minus 252.8 degrees Celsius)–and liquid oxygen.

Detailed explanation-3: -The rocket’s main engines use a combination of liquid hydrogen and liquid oxygen.

Detailed explanation-4: -Unlike rocket boosters previously used in the space program, the space shuttle’s solid rocket booster casings and associated flight hardware are recovered at sea. The expended boosters are disassembled, refurbished and reloaded with solid propellant for reuse.
