Answer 2

Answer:

The smallest prime number is 2 , which is also the only even prime.

4 is the smallest composite number.

The smallest odd composite number is 9

9,15, 21, 25, 27 are odd composite numbers.

4, 6, 8, 10, 12, 14, 16, are even composite numbers

1 is neither prime nor composite.

Because 1 has only one positive divisor (1 itself), it does not meet the criteria to be a prime. Similarly, a composite number is a number that can be rewritten as the product of two integers both larger than 1, and 1 does not meet that criteria.
