Answer 1

is it correct?

Answer 2

A and C make no sense at all, since A n B means the ones they both have in common

and A U B means all the things in both A and B

\[A \subseteq B\] means all the things in A, are also in B (but not necessarily vice versa)

Answer 3

so its correct because all things in A are also in B

Answer 4

And all the things in B can't possibly be in A, cos B is bigger than A.

Answer 5

no all the things in A are in B
