Answer:
4) c
6) a, b
7) a
8) b, c
10) I'm not sure but I believe it is C.
Step-by-step explanation:
Let a ∈ A. Then a is some integer that is divisible by 4, so we can write a = 4k for some integer k.
We can simultaneously rewrite a as a = 2•2k, so 2 clearly divides a, which means a ∈ B as well.
Therefore A ⊆ B.
