(C) The total number of subsets of a set $A$ with $n$ elements is given by the formula $2^n$.Here,the set $A = \{ 1, 2, 3, 4, 5 \}$ has $n = 5$ elements.Therefore,the total number of subsets is $2^5 = 32$.$A$ proper subset is any subset of $A$ except the set $A$ itself.Thus,the number of proper subsets is $2^n - 1$.Substituting $n = 5$,we get $2^5 - 1 = 32 - 1 = 31$.

If $A = \{ 1, 2, 3, 4, 5 \}$,then the number of proper subsets of $A$ is
