Answer and explanation
Correct answer: B ⊆ A; B is a subset of A
The set B contains the elements 2 and 4. Both of these elements are present in A = {1, 2, 3, 4}; therefore every element of B belongs to A, which proves B ⊆ A. The sets are not equal because A also contains 1 and 3. Also, 2 is an element of B, not a subset of B.
