The correct answer is D) There would likely not be life on Earth because its surface would be much colder and Earth's water would be frozen.
Life on Earth could be affected if the atmosphere did NOT contain greenhouse gases in the following way: "There would likely not be life on Earth because its surface would be much colder and Earth's water would be frozen."

Without these gases, the surface of the earth would have an average temperature of minus 18 centigrades. Many life forms as we know them could not survive under this hairs climate condition. Furthermore, most of the surface of the earth would be covered on ice.
