Earth is the only planet in the given options that can support life. It has a suitable atmosphere, water in liquid form, and a moderate temperature range, which are essential for the existence of life as we know it. Additionally, Earth is located in the habitable zone of our solar system, where conditions are favorable for the development and sustenance of life. Mercury, Venus, and Mars do not possess these necessary conditions, making Earth the correct answer.

Jupiter is the largest planet in the Solar System. It has a diameter of about 86,881 miles, which is more than 11 times the diameter of Earth. 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.

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.

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.

Venus is called the 'evening star' because it is often visible in the evening sky after sunset. It is one of the brightest objects in the night sky and can be easily seen during certain times of the year. Venus is often referred to as the 'evening star' or the 'morning star' because it is visible either in the evening or in the early morning hours before sunrise.
