The correct answer is: Lumen of thylakoids
According to the chemiosmotic hypothesis, the splitting of water occurs in the lumen of the thylakoid, hence leading to the accumulation of H+ ions in the lumen itself. This creates the proton gradient across the membrane leading to the ATPase pump activity.
