c. cryosphere
d. exosphere

Option A. The Biosphere is the Earth system that is mot responsible for the increases in global warming.

Explanation:

Global warming is the continue increase of the average global temperature. In the last 50 years records show that the Earth's temperature has increased at the fastest rate in all recorded history. This occurs due to carbon dioxide and other air pollutants known as greenhouse gases being collect and trapped in the atmosphere and by absorbing sunlight and solar radiation they bounce off the Earth's surface but cannot escape the planet. Global warming is a 100 percent human-made process; therefore the biosphere is the Earth's layer or system that is the most responsible for the increase of global warming. The biosphere is the layer of Earth where life exists, encompassing animals, flora, and of course, humans.
