Answer 1

Answer: (B), (C)

The correct options are
B The outer planets are made up of gases and liquids.
C All outer planets have at least one moon.

Outer planets are farther from the Sun when compared to the inner planets and thus, we can say outer planets are colder than inner planets. The four outer planets—Jupiter, Saturn, Uranus, and Neptune—are gas giants made primarily of hydrogen and helium. They have thick gaseous outer layers and liquid interiors. All of the outer planets have numerous moons, as well as planetary rings made of dust and other particles.
