It is an outer planet.

Explanation

Earth formed from a disk of gas and dust surrounding the young Sun. It is a rocky inner planet, not an outer or gaseous planet, and its atmosphere is mostly nitrogen and oxygen rather than hydrogen and helium. Therefore, “It was formed from gas and dust” is the correct statement.
