Consider the following statements and choose the statement/s which are not true.:
I – Neutral function possible with n variable is 2nC2n – 1.
II – In neutral function number of minterms = number of maxterms + 1.
III – Number of Dual function is 22n.
IV – To find the Dual function of a given function replace OR with AND and AND with OR, 0 with 1 and 1 with 0.

(A) I and III
(B) II and IV
(C) II and III
