Answer: The correct answer to the question is option (b) "trap thermal energy in the atmosphere." Greenhouse gases, like water vapor and carbon dioxide, play an essential role by trapping some of the thermal energy that would otherwise escape back into space. This trapped heat helps to warm the Earth's surface, maintaining a climate that can support a wide variety of life.
