  Neptune
- C.
  
  Jupiter
- D.
  
  Venus
Correct Answer
D. Venus

Explanation
Venus is the correct answer because it has a thick atmosphere composed mainly of carbon dioxide, which creates a greenhouse effect. This traps heat from the sun, causing Venus to have an average surface temperature of about 900 degrees Fahrenheit (475 degrees Celsius), making it the hottest planet in the solar system.

Uranus is a gaseous planet because it is composed primarily of hydrogen and helium gases. It is classified as a gas giant, along with Jupiter and Saturn, due to its large size and predominantly gaseous composition. Unlike Earth and Mars, which are rocky planets, Uranus does not have a solid surface and is instead made up of thick layers of gas. Mercury, on the other hand, is a small and rocky planet, making it distinct from Uranus.

Jupiter's massive size is due to its composition, primarily consisting of hydrogen and helium. It also has a strong gravitational pull, which allows it to capture and retain a large number of moons. Additionally, Jupiter's iconic feature is its Great Red Spot, a massive storm that has been observed for over 300 years. Overall, Jupiter's size and unique characteristics make it the largest planet in our Solar System.
