The correct option is C glucose and oxygen
Green plants use sunlight to make their food and the process is called photosynthesis. It requires sunlight, chlorophyll, water, and carbon dioxide gas. The chlorophyll present in leaves absorbs light energy from the sun and converts it into chemical energy.
Glucose is the simple food which is prepared first in the process of photosynthesis. Glucose and oxygen (formed during splitting of water) are the final products of photosynthesis. The glucose is stored in the form of starch in the plant cells.
