Answer:
Synthesis of ATP would be directly affected (correct answer A)
Explanation:
While photosynthesis and the electron transport in thylakoid-membrane occur, a gradient in proton concentration is made. Then, this protons go through a protein complex (ATPasa, present in thylakoid membrane) down a concentration gradient into stroma, and this potential energy is used to synthesize ATP (energy for the cell).
