The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about the association of the splitting of water in the process of photosynthesis. 2. **Identifying the Location**: The splitting of water occurs in the thylakoid membranes of chloroplasts, which are the sites of the light-dependent reactions of photosynthesis. 3. **Photosystems Involved**: There are two main photosystems involved in the light reactions: Photosystem I (PSI) and Photosystem II (PSII). The splitting of water is specifically associated with Photosystem II. 4. **Chemical Reaction**: The splitting of water (photolysis) can be represented by the equation: \[ 2H_2O \rightarrow 4H^+ + O_2 + 4e^- \] This reaction occurs in the presence of manganese ions (Mn²⁺) and chloride ions (Cl⁻) on the inner surface of the thylakoid membrane. 5. **Conclusion**: Therefore, the splitting of water is associated with Photosystem II (PSII) and occurs on the inner surface of the thylakoid membrane. 6. **Final Answer**: The correct association for the splitting of water is with Photosystem II (PSII) on the inner surface of the thylakoid membrane. ---
