Jupiter is a gas giant planet and the largest planet in the solar system. Its mass is 2.5 times the total mass of the other seven planets in the solar system. Observations have found that most of the more than 70 moons surrounding Jupiter are composed of water ice. Therefore, Jupiter's atmosphere should contain a considerable amount of water.
The statement "Uranus is also a gas giant planet, and it has been confirmed that it contains a lot of water ice" can best support the above statement.
