Question

E = {A, D, E, K} is a subset of which of the following sets?

Answer 1

A is a subset of a set B if all elements of A are also elements of B.

With this in mind we notice that E is a subset of the set:

`\lbrace D,B,C,K,L,Z,A,E\rbrace`

since all the elements of E are there.

Therefore the answer is the second option.
