Answer

To solve the question of what a person deficient in the visual pigment rhodopsin should be advised to take more of, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Rhodopsin**:
- Rhodopsin is a visual pigment found in the retina of the eye that is crucial for vision in low-light conditions. It is composed of a protein called opsin and a chromophore called retinal, which is derived from vitamin A.

2. **Identifying the Cause of Deficiency**:
- A deficiency in rhodopsin is often linked to a deficiency in vitamin A. Therefore, to improve rhodopsin levels, one should consume foods rich in vitamin A.

3. **Analyzing the Options**:
- **Option 1: Radish and Potato**: These are rich in vitamin C but not in vitamin A.
- **Option 2: Carrot and Ripe Papaya**: Carrots are well-known for their high vitamin A content, and papayas also contain vitamin A along with vitamin C.
- **Option 3: Guava and Ripe Banana**: Guavas are rich in vitamin C and fiber, while bananas are primarily sources of potassium and vitamin C, but not significant in vitamin A.
- **Option 4: Apple and Grapes**: Both are rich in vitamin C and other nutrients but lack vitamin A.

4. **Selecting the Best Option**:
- Since the goal is to increase rhodopsin levels through vitamin A intake, the best option is **Carrot and Ripe Papaya**. Carrots are particularly noted for their high beta-carotene content, which the body converts into vitamin A.

5. **Conclusion**:
- Therefore, a person deficient in the visual pigment rhodopsin should be advised to take more **Carrot and Ripe Papaya**.

### Final Answer:
A person deficient in the visual pigment rhodopsin should be advised to take more of **Carrot and Ripe Papaya**.
