Q. The circuit diagram shows a logic combination with the states of output X, Y and Z given for inputs P, Q, R and S all at state 1. When inputs P and R change to state 0 with inputs Q and S still at 1, the states of outputs X, Y and Z change to

A) 1, 0, 0
B) 1, 1, 1
C) 0, 1, 0
D) 0, 0, 1
Explanation

(c) In that states output X, Y and Z changes to 0, 1, 0.
