Choose the odd one from the given four choices.

Options

A. 64
B. 96
C. 121
D. 144

Explanation

To solve the problem of choosing the odd one out from the given four choices, we will analyze each option to determine whether they are perfect squares or not.

### Step-by-Step Solution:

1. **Identify the Options**:
Let's denote the options as follows:
- Option 1: 121
- Option 2: 96
- Option 3: 144
- Option 4: 12

2. **Check if Each Option is a Perfect Square**:
- **Option 1: 121**
- Calculate the square root of 121:
\[ \sqrt{121} = 11 \]
- Since 11 is an integer, 121 is a perfect square.

- **Option 2: 96**
- Calculate the square root of 96:
\[ \sqrt{96} \approx 9.798 \]
- Since 9.798 is not an integer, 96 is not a perfect square.

- **Option 3: 144**
- Calculate the square root of 144:
\[ \sqrt{144} = 12 \]
- Since 12 is an integer, 144 is a perfect square.

- **Option 4: 12**
- Calculate the square root of 12:
\[ \sqrt{12} \approx 3.464 \]
- Since 3.464 is not an integer, 12 is not a perfect square.

3. **Summarize the Findings**:
- Option 1 (121) is a perfect square.
- Option 2 (96) is not a perfect square.
- Option 3 (144) is a perfect square.
- Option 4 (12) is not a perfect square.

4. **Determine the Odd One Out**:
- From the analysis, we see that Options 1 (121) and 3 (144) are perfect squares, while Option 2 (96) is not a perfect square. Option 4 (12) is also not a perfect square, but since we are looking for the odd one out, we can see that Option 2 (96) is the only number that is not a perfect square among the others.

### Conclusion:
The odd one out is **Option 2: 96**.
