Answer:
Option (B) is the correct one.
Explanation:
While taking dual we reverse all the relative operations,so AB becomes B+A
and (B+C) becomes BC.
Using this logic,
XY, YZ will become X+Y and Y+Z respectively.
And since we initially had their sum i.e they were passes through OR gate we need to change it to their product i.e pass them through AND gate,
So the last expression becomes,
(X+Y)(Y+Z)
