उत्तर
The natural number 1 is neither prime nor composite.
Explanation:
A prime number has exactly two distinct positive divisors (1 and itself), while a composite number has more than two and can be written as a product of primes (Fundamental Theorem of Arithmetic). The number 1 has only one positive divisor (1), so it is neither prime nor composite.
