This statement directly compares two planets, Venus and Mercury, and shows that Venus, with its thick atmosphere rich in greenhouse gases, has a higher average temperature than Mercury, which has almost no atmosphere. This provides strong observational support for the claim that greenhouse gases make a planet warmer than it would be otherwise. The other statements (A, B, C) do not necessarily relate to greenhouse gases or their effects on planetary temperature.
