C
Our moon is one of the smallest in the solar system. There are only 2 satellites smaller.

Explanation: 

Detailed explanation-1: -The composition of the Moon is much like that of the Earth. Its rocks are similar to Earth rocks and contain many but not all of the same minerals. However, the Moon has no atmosphere, it shows no trace of past or present life, and its rocks contain no water.

Detailed explanation-2: -People may be tempted to compare Mercury and the moon because one’s surface looks much like the other’s. Both Mercury and the moon have surfaces, or crusts, composed almost entirely of rock and pocked with craters.

Detailed explanation-3: -In contrast, accretion theory suggested that the Moon was created along with Earth at its formation. Finally, according to the fission scenario, Earth had been spinning so fast that some material broke away and began to orbit the planet. What is most widely accepted today is the giant-impact theory.

Detailed explanation-4: -Unlike the other big moons like Ganymede, Titan, Europa, Callisto and Triton, our Moon lacks any real atmosphere and isn’t covered in ice. Sure, it is a lot closer to the Sun, so maybe it lost much of its ice (there is some), but it is a much more desolate locale compared to the icy moons of the solar system.
