Options

A. PS II
B. PS I
C. Carotenoid
D. `P_(700)`

Answer

To answer the question "The photosystem connected with splitting of water is," we will analyze the options provided and the roles of the photosystems in the process of photosynthesis.

### Step-by-Step Solution:

1. **Understanding Photosystems**:
- In photosynthesis, there are two main photosystems: Photosystem I (PS1) and Photosystem II (PS2). Each photosystem plays a distinct role in the light-dependent reactions of photosynthesis.

2. **Identifying the Role of Photosystem II**:
- Photosystem II (PS2) is known for its role in the initial steps of the light reactions. It acts as a strong oxidizing agent and is crucial for the splitting of water molecules (photolysis).

3. **Water Splitting Process**:
- During the light reactions, water (H2O) is split into oxygen (O2), protons (H+), and electrons (e-). This process occurs at Photosystem II. The reaction can be summarized as:
\[ 2 H_2O \rightarrow 4 H^+ + 4 e^- + O_2 \]

4. **Conclusion**:
- Given that Photosystem II is responsible for the splitting of water, the correct answer to the question is **Photosystem II (PS2)**.

### Final Answer:
The photosystem connected with splitting of water is **Photosystem II (PS2)**.
