Which of the following is not a statement.

Options

A. Smoking is injurious to health
B. 2+2 = 4
C. 2 is the only even prime number
D. Cone here

Explanation

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

Let's analyze the given options step by step:

1. **Option 1: "Smoking is injurious to health."**
- This is a declarative sentence that can be evaluated as true (it is generally accepted as true).
- Therefore, this is a statement.

2. **Option 2: "2 plus 2 is 4."**
- This is also a declarative sentence that can be evaluated as true (the mathematical operation is correct).
- Therefore, this is a statement.

3. **Option 3: "2 is the only even prime number."**
- This is a declarative sentence that can be evaluated as true (it is a known fact in mathematics).
- Therefore, this is a statement.

4. **Option 4: "Come here."**
- This is an imperative sentence (an order or command) and does not have a truth value; it cannot be classified as true or false.
- Therefore, this is not a statement.

Based on the analysis, the option that is not a statement is **"Come here."**

### Final Answer:
"Come here" is not a statement.
