(ii) `2332`

(iii) `5684`
(iv) `6908`
(v) `50699`

Answer

To determine which of the given numbers can be the square of a number based on the unit's place digit, we need to follow these steps:

### Step-by-Step Solution:

1. **Understand the Unit's Place of Squares**:
The unit digit of a perfect square can only be one of the following digits: 0, 1, 4, 5, 6, or 9.

2. **Check Each Number**:
- **(i) 3051**: The unit's digit is 1. Since 1 is in the list of possible unit digits for squares, 3051 can be a square.
- **(ii) 2332**: The unit's digit is 2. Since 2 is not in the list, 2332 cannot be a square.
- **(iii) 5684**: The unit's digit is 4. Since 4 is in the list, 5684 can be a square.
- **(iv) 6908**: The unit's digit is 8. Since 8 is not in the list, 6908 cannot be a square.
- **(v) 50699**: The unit's digit is 9. Since 9 is in the list, 50699 can be a square.

3. **Conclusion**:
Based on the unit digits, the numbers that can be squares are:
- 3051
- 5684
- 50699

### Final Answer:
The numbers that can be the square of a number are: **3051, 5684, and 50699**.
