- a composite number.
- prime as well as composite.
- neither prime nor composite.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
A prime number is a natural number greater than 1 with exactly two factors (1 and itself).
A composite number is a natural number greater than 1 with more than two factors.
Step 2: Detailed Explanation:
The number 1 only has one factor, which is 1 itself.
Since it does not have exactly two distinct factors, it is not prime.
Since it does not have more than two factors, it is not composite.
By definition, 1 is excluded from the categories of both prime and composite numbers.
Step 3: Final Answer:
The natural number 1 is neither prime nor composite.
A prime number is a natural number greater than 1 with exactly two factors (1 and itself).
A composite number is a natural number greater than 1 with more than two factors.
