What is the order of terrestrial planets in our solar system?

The order of terrestrial planets in our solar system is accurately represented by the choice that lists Mercury, Venus, Earth, and Mars in that sequence. Terrestrial planets are defined as those that are primarily composed of rock and metal, and they have solid surfaces.

Mercury is the closest planet to the Sun, followed by Venus, which is often referred to as Earth's sister planet due to its similar size and composition. Earth, which supports life, comes next in this order. Mars, known as the "Red Planet," is further out in the solar system and is the last of the terrestrial planets.

This sequence emphasizes their relative positions to the Sun, as well as their classification based on physical characteristics. The other choices contain planets that are categorized as gas giants or are arranged in a manner that does not accurately reflect the actual sequence of the terrestrial planets within our solar system.
