Answer

Given set : {{1, {0}}, 2}

The set A = {{1, {0}}, 2} has two elements : {1, {0}} and 2.

Thus, n = 2.

The number of subsets of a set with n elements = 2n = 22 = 4.

Thus, statement 1 is false.

We know that,

The total number of proper subsets of a set with n elements is 2n - 1.

Thus, statement 2 is true.

Hence, option 4 is the correct option.
