Question

Which one of the following is true? (A) ∅ ∈ (B) ⊂ ∩ (C) ∅ ∈ () (D) none of them.​

Answer 1

Answer:

Correct option is

A

B∈A

Since A is the power set of B then B∈A as the power set always contains the original set according to the definition of power set.

Also neither A⊂B nor B⊂A as the element of A are subsets and the elements of A are not subsets but arbitrary elements.
