<u>ANSWER</u>:- option A formation of fossil fuels.
<u>Explanation</u>:-
- Fossil fuels are formed from dead and decaying plants and animal.
- When the dead and decaying plants and animals are exposed to heat and pressure over a long period of time they get converted to oil, coal, gas etc.
- These oil ,coal, gas are called as fossil fuels.
- The entire process of formation of fossil fuels can take place over a million of years.
- In contrast to the formation of fossil fuels , the process of photosynthesis in plants, respiration in animals and emission of waste is a phenomena which occurs at daily basis and over a short interval of time.
So, <em>the formation of fossil fuels is the phenomena which takes the longest time in the carbon cycle.</em>
