first of all, you should understand what is the meaning of , and ?
: A is subset of B. means, all elements of set A are elements of set B.
: A is not subset of B. means, all elements of setA are not elements of set B.
: A belongs to B. means, set A is the element of set B.
now come to the question,
given, set A = {1, 2, {3, 4} , 5}.
Let us assume B = .
here it is clear that set B is not element of set A. [ actually, it happens when A = {∅, 1, 2, {3, 4}, 5} ]
so, we can write it
thus, the statement is incorrect.
