@raywolf1250 what is a composite number? What is a prime number? Can a number be both prime and composite at the same time?

Consider 16+17=33
That is not the answer because 33 is a composite number since 33 = 3(11)

Now consider the other answers and pick the sum whose answer is NOT composite. Therefore the answer is prime. Pick the one whose answer is prime.
