Q. 58 A Boolean function f of two variables x and y is defined as follows :
f (0,0) = f (0,1) = f (1,1) = 1; f (1,0) = 0
Assuming complements of x and y are not available, a minimum cost solution for realizing f using only 2-input NOR gates and 2- input OR gates (each having unit cost) would have a total cost of
(A) 1 unit
(B) 4 unit
(C) 3 unit
(D) 2 unit
