Which of the following is not correct?

Options

A. `N subR`
B. `NsubQ`
C. `QsubR`
D. `NsubT`

Answer

To determine which of the statements is not correct, we will analyze each option step by step.

### Step 1: Understand the Sets Involved
- **Natural Numbers (N)**: The set of positive integers starting from 1, i.e., N = {1, 2, 3, ...}.
- **Rational Numbers (Q)**: The set of numbers that can be expressed as the quotient of two integers, where the denominator is not zero.
- **Real Numbers (R)**: The set of all numbers that can be found on the number line, including both rational and irrational numbers.

### Step 2: Analyze Each Statement
1. **Statement A**: N is a subset of R.
- **True**: All natural numbers are real numbers.

2. **Statement B**: N is a subset of Q.
- **True**: All natural numbers can be expressed as fractions (e.g., 1 = 1/1), so they are rational numbers.

3. **Statement C**: Q is a subset of R.
- **True**: All rational numbers are real numbers.

4. **Statement D**: N is a subset of T (where T is not defined in the question).
- **False**: Without knowing what T represents, we cannot confirm that natural numbers are a subset of T. Thus, this statement is likely incorrect.

### Conclusion
Based on the analysis, the statement that is not correct is **Statement D**.

### Final Answer
The answer is **Statement D** is not correct.
