C
Stars are massive objects composed of gas.
D
Stars are solid objects that we could stand on.
E
Stars are composed primarily of hydrogen and helium.
F

Explanation

Stars produce energy mainly through nuclear fusion, which combines light atomic nuclei and releases energy. They are massive balls of hot gas, made primarily of hydrogen and helium. Gravity holds a star together, but it is not the process that produces its energy; stars are not solid objects or made mostly of liquid water.
