Which of the following is a statement?

Options

A. 2 is not a prime number.
B. Mind your own business.
C. Be punctual.
D. Do not tell lies.

Answer

To determine which of the given options is a statement, we need to understand what constitutes a statement in mathematical reasoning. A statement is a declarative sentence that can be classified as either true or false, but not both.

### Step-by-Step Solution:

1. **Understand the Definition of a Statement**:
- A statement is a declarative sentence that is either true or false, but not both.

2. **Analyze Each Option**:
- **Option A**: "2 is not a prime number."
- This statement can be evaluated. The number 2 is actually a prime number (the only even prime number). Therefore, this statement is false. Since it can be classified as false, it qualifies as a statement.

- **Option B**: "Mind your own business."
- This is an imperative sentence and does not convey a truth value. It cannot be classified as true or false, so it is not a statement.

- **Option C**: "Be punctual."
- Similar to option B, this is also an imperative sentence. It does not have a truth value and cannot be classified as true or false, so it is not a statement.

- **Option D**: "Don't tell lies."
- This is another imperative sentence. Like the previous two options, it does not have a truth value, so it is not a statement.

3. **Conclusion**:
- After analyzing all the options, the only option that qualifies as a statement is **Option A: "2 is not a prime number."**

### Final Answer:
The statement is **Option A: "2 is not a prime number."**
