C. this depends on the number whose square is being calculated
D. can not determine

Answer

To solve the question "The square of an odd number is ……….", we will analyze the properties of odd numbers and their squares.

### Step-by-Step Solution:

1. **Understanding Odd Numbers**:
- Odd numbers are integers that cannot be divided evenly by 2. Examples include 1, 3, 5, 7, 9, etc.

2. **Finding the Square of Odd Numbers**:
- To find the square of an odd number, we can take any odd number and multiply it by itself.
- For example:
- The square of 1: \(1 \times 1 = 1\) (which is odd)
- The square of 3: \(3 \times 3 = 9\) (which is odd)
- The square of 5: \(5 \times 5 = 25\) (which is odd)
- The square of 7: \(7 \times 7 = 49\) (which is odd)

3. **Generalizing the Result**:
- From the examples, we can observe that squaring any odd number results in another odd number.
- Therefore, we can conclude that the square of an odd number is always odd.

4. **Final Answer**:
- The square of an odd number is **odd**.
