6 is a natural no
let me go

Options

A. x is a real number
B. Switch off the fan
C. 6 is a natural number
D. Let me go

Explanation

To determine which of the given options is a statement, we need to understand what a statement is. A statement is a declarative sentence that is either true or false, but not both. Let's analyze each option one by one.

1. **Option: x is a real number**
- Here, "x" is a variable and does not specify a particular value. Since we cannot determine whether this is true or false without knowing the value of "x", this is **not a statement**.

2. **Option: switch off the fan**
- This is an imperative sentence, which is a command or request. It does not convey a truth value (true or false), so this is also **not a statement**.

3. **Option: 6 is a natural number**
- This is a declarative sentence that can be evaluated for its truth value. Since 6 is indeed a natural number (natural numbers are defined as positive integers starting from 1), this statement is **true**. Therefore, this is a **statement**.

4. **Option: let me go**
- Similar to the second option, this is also an imperative sentence. It does not express a truth value, so it is **not a statement**.

Based on the analysis, the only option that qualifies as a statement is:

**Answer: 6 is a natural number.**
