Hello,

I am confused about how the set A is formed. Is this dividing two sets?

Let A, B and O be the following sets: A :={composite numbers)=(2,3,4,5,6,7,8, ..}{prime numbers)=(4,6,8,9,10, ..} B :=(positive odd numbers} and C:=(positive integers less than or equal to 10). The set D : = (AUB)nC is Select one: O (2,3,4,5,6,7,8,10) O {1,3,4,5,6,7,8,9,10} O (1,3,5,7,9,... } O {2,3,4,5,6,7,8,9,10}
