c. 2, 3

d. All of the above

ANSWER: 1, 2

Explanation:

Jupiter is a gas giant, along with Saturn, with the other two giant planets, Uranus and Neptune, being ice giants.

An ice giant is a giant planet composed mainly of elements heavier than hydrogen and helium, such as oxygen, carbon, nitrogen, and sulfur.

Since 2014, there has been theoretical evidence of the existence of a possible third ice giant, which, if it exists, would be the Solar System's ninth planet.
