The greenhouse effect is caused by gasses such as carbon dioxide and water vapor, which absorb heat and reradiate the the heat back to the earth. Since in the greenhouse effect heat is retained, the greenhouse gasses act as thermal insulators to the Earth. These effect also moderates the temperatur on Earth. Having said this, the answer is D.
