Answer:
B: greenhouse
Explanation:
Water vapor traps heat in the Earth's atmosphere. This serves to maintain Earth's atmospheric temperature. Based on this function, water can be classified as a greenhouse gas.
Greenhouse gases can be defined as gases that trap heat within the Earth's atmosphere. Thus, an increase in global temperature is largely caused due to an increase in the amount of greenhouse gases in Earth's atmosphere.
Some examples of greenhouse gases present in the atmosphere are methane, water vapor, carbon dioxide etc.
I believe that the best answer for this question would be sanguine. People who fall under the category of the sanguine temperament tend to be lively, pleasure-seeking, talkative, and highly social. They can easily fall in love and may be flighty and forgetful. You can also reach this conclusion by ruling out the others; choleric individuals are angry and impulsive, melancholic individuals are introverted and solemn, and phlegmatic individuals are thoughtful and calm. Hope this helps.
