2 is the exception to the rule that every prime number is odd

Because every number is either odd or even. Even numbers are divisible by two, which means that (with the exception of 2 itself) they by definition are not prime.

The lowest odd prime number is 3 .

That's not true.

No because as for example 39 is an odd number but it is also a composite number because it has more than two factors and prime numbers have only two factors.

Because every number is either odd or even. Even numbers are divisible by two, which means that (with the exception of 2 itself) they by definition are not prime.

All even numbers are, by definition, multiples of 2 and therefore are not prime. It follows that every prime number (other than 2) is odd as a prime number is defined as one which is not the multiple of any other integers. This is not to say that all odd numbers are prime. Odd and prime: 3, 5, 7, 11, 13, 17, 19 etc...
