- A.
  
  True

  False
Correct Answer
A. True

Explanation
Mercury has no air because it has a very thin atmosphere consisting mostly of trace amounts of helium and hydrogen. The planet's proximity to the Sun means that the high temperatures cause any gases to escape into space. The lack of air on Mercury is due to its small size and weak gravity, which cannot hold onto gases as effectively as larger planets like Earth.
