Solution

The correct option is D Photophosphorylation
The stacks of thylakoids are called grana. They are connected with an extensive system of tubules. The thylakoid membranes contain chlorophyll and other pigments arranged in antenna arrays to capture light energy for two photosystems called as photosystem I and photosystem II. In most plants, both photosystems are used in an electron transport process, that yields energy in the form of ATP (photophosphorylation) and reduced coenzymes to the stroma of the chloroplast to be used in the synthesis of carbohydrates.
