The circuit diagram (see fig.) shows a 'logic combination' with the states outputs `X,Y` and `Z` given for input `P,Q,R` and `S` all at state `1` (i.e., high). When inputs `P` and `R` change to state `0` i.e., low) with inputs `Q` and `S` still at `1`, the condition of output `X,Y` and `Z` chages to

Options

A. 1, 0, 0
B. 1, 1, 1
C. 0, 1, 0
D. 0, 0, 1

Answer

C

Explanation

In that states outputs X, Y and changes to 0, 1, 0.
