@luckythebest

Answer 2

B?

Answer 3

the logic is same as last sum. :P

Answer 4

Obviously B is a subset of A U B
A U B is a subset of B because if an element x is in B, then obviously, it is in B
and if an element x is in A, then it is in B since A is contained in B.

Answer 5

hence equal

Answer 6

wouldn't it be the element that are in both A and B

Answer 7

Thank you sir

Answer 8

that is actual A is contained in B not A is a subset of B. The signs are totally different
