Prove that for all sets A and B, ((A) / (B)) ∪ ((B) / (A)) = (A ∪ B) / (A ∩ B). If A is the set of even integers and B is the set of integers that are multiples of 3, which of the following options correctly describes this equation?

A) ((A) / (B)) ∪ ((B) / (A)) = (A ∪ B) / (A ∩ B)
B) ((A) / (B)) ∪ ((B) / (A)) = (A ∪ B) / (A ∩ B)
C) ((A) / (B)) ∪ ((B) / (A)) = (A ∪ B) / (A ∩ B)
D) ((A) / (B)) ∪ ((B) / (A)) = (A ∪ B) / (A ∩ B)
