Best answer
Right option is (d) Photosynthesis

For explanation: Photosynthesis is the phenomenon responsible for the initiation of a food chain. 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.
