Answer:
B) light dependent reaction: electron transport and the splitting of water
Explanation:
The source of ATP and NADPH, which are required to synthesize glucose is a light-dependent reaction.
During the process of photosynthesis, light energy is required to tranport electrons that produces ATP and NADPH and splitting of water, generating O2.
Photosystem I (PSI) absorbs the light energy and electrons supplied from PSII (Photosystem II) are transferred to the protein ferredoxin, which further donates electrons to electron transport chain that produces ATP and to the electron carrier NADP+ to form NADPH.
Hence, the correct option is B.
