C. natural numbers
D. odd numbers

Answer

To solve the question "N numbers are called", we need to identify what "N" represents in the context of number systems in mathematics.

### Step-by-Step Solution:

1. **Understanding the Context**: We need to determine what "N" denotes in mathematics. The question suggests that "N" is associated with a specific type of numbers.

2. **Identifying Common Number Sets**: In mathematics, there are several common sets of numbers:
- **Natural Numbers (N)**: These are the set of positive integers starting from 1 (1, 2, 3, ...).
- **Whole Numbers (W)**: These include all natural numbers and 0 (0, 1, 2, 3, ...).
- **Integers (Z)**: These include all whole numbers and their negative counterparts (..., -3, -2, -1, 0, 1, 2, 3, ...).
- **Rational Numbers (Q)**: These are numbers that can be expressed as a fraction of two integers.
- **Real Numbers (R)**: This includes all rational and irrational numbers.

3. **Identifying the Denotation for N**: In standard mathematical notation:
- "N" specifically denotes **Natural Numbers**.

4. **Conclusion**: Based on the identification, we can conclude that "N numbers are called Natural Numbers".

### Final Answer:
N numbers are called **Natural Numbers**.
