Isn't statement no.2 just ridiculous ?

How on earth can 1 be regarded as a "PRIME NUMBER"

One is neither Prime nor Composite.

No, it is not at all ridiculous

Definition of Prime Number

A Prime number is a natural number with exactly two distinct natural number divisors: 1 and itself. Otherwise a number is called a composite number. Therefore, 1 is not a prime, since it only has one divisor, namely 1. A number n>1 is prime if it cannot be written as a product of two factors a and b, both of which are greater than 1: n = ab. |

Statement 2 is sufficient to state the x is a prime number...

Completely Disagree..!!!

How can someone say that 1 is a prime factor of a number.

One is neither prime nor composite.

In a way your statement is supporting my claim

statement 2 states => All the prime factors of x are 1 and itself.

How can one be a prime factor

The statement should be => All the factors of x are 1 and itself.

Big Difference

Yes, I agree. I missed that point. My Bad.

1 is a factor of a prime number BUT NOT a prime factor. 1 is neither prime nor composite.

Either the OA marked is incorrect or the question is incorrect.
