The correct answer is C. The burning of fossil fuels.
Explanation
The carbon cycle is a cycle in which carbon interacts with the biosphere, the lithosphere, the hydrosphere, and the Earth's atmosphere. Knowledge about this carbon circulation makes it possible to appreciate human intervention in the climate and its effects on climate change. This cycle makes life on Earth possible because the plants consume carbon dioxide, however, the balance of this cycle has been altered by the massive use of fossil fuels such as oil, gasoline, and gas. This alteration causes the atmosphere to deteriorate causing the sun's rays to directly penetrate the earth, on the other hand, it causes the greenhouse effect to increase, causing the earth's temperature to rise. So, the correct answer is C. The Burning of fossil fuels.
