Right choice is (c) 4 × 10^13 kg
 
Explanation: Photosynthesis is a process in which producers (green plants) in the presence of CO2, water, sunlight, and chlorophyll yield energy and oxygen is released in the form of gas. The amount of carbon fixed in the biosphere through photosynthesis annually is approximately 4 × 10^13 kg.
