Concept:Prime numbers have exactly two distinct factors (1 and itself). Composite numbers have more than two factors. The number 1 has only one factor.Explanation:A prime number must have exactly two different factors: 1 and the number itself. Since 1's only factor is 1, it does not meet this condition.A composite number must have at least three factors. Since 1 has only one factor, it is not composite either.Thus, 1 is neither prime nor composite.Answer:Option B: 1 is neither prime nor a composite number
