B doesn't come into it any more than C.

B is irrelevant to a statement about A and B? Huh.

Yes, it is irrelevant. Either A or B is irrelevant in the formation of a union in which only either A or B has elements in common with x.

C is a {banana,orange}. DO YOU SEE WHAT I AM GETTING AAAT??? Sorry to shout, but do you see what I am getting at?

No, and neither will anyone else - your comment about C has no
relevance whatever.

Okay, you don't see what I am getting at. Try this:
IF a union of A and B is described only in terms of either A or B, then how can a union be a union of A AND B?
ie. how can you have a union of EITHER A OR B?

[C comes into it because if the union is only of either A or B, then C can be associated with either term. Honestly, your definition must be wrongly transcribed.]
