Which of the following statements about Neptune is true?

The statement that all the given options are true highlights key aspects of Neptune's characteristics. Neptune is indeed considered a "twin" to Uranus due to their similar sizes, compositions, and distances from the Sun. Both planets belong to the category of ice giants, which is a classification given due to the presence of water, ammonia, and methane ice in their atmospheres.

Furthermore, Neptune is known for its intense and dynamic atmosphere, which features some of the strongest winds recorded in the solar system, reaching speeds of up to 1,250 mph. This fast-moving atmosphere contributes to the planet's extreme weather patterns, including massive storms and high-speed jets.

Additionally, while the atmosphere of Neptune does contain significant amounts of hydrogen and helium, it is also rich in other compounds such as methane, which gives the planet its striking blue color. This rich composition is a defining feature of Neptune, differentiating it from gas giants like Jupiter and Saturn.

Since each statement regarding Neptune's characteristics is accurate, the comprehensive choice that includes all these truths is the correct answer.
