Solution

The correct option is C electron transfer
Z-scheme of the light-dependent reactions happen in the thylakoid membrane of the chloroplasts and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions. It is concerned with electron transfer along with the synthesis of ATP and NADPH.
