first of all, you should understand what is the meaning of A\subset B, A\not\subset B and A\in B ?

A\subset B : A is subset of B. means, all elements of set A are elements of set B.

A\not\subset B : A is not subset of B. means, all elements of setA are not elements of set B.

A\in B : A belongs to B. means, set A is the element of set B.

given, A = {1, 2, {3, 4}, 5}
here we can see that 1 is an element of set A.
so, we can say that 1 belongs to A. e.g., 1\in A and also we can say that 1 is not a subset of setA.e.g., 1\not\subset A
Thus, the statement is incorrect.
