Figure gives a system of logic gates. From the study of truth table it can be found that no produce a high output `(1)` at `R`, we must have

A

`X=0, Y=1`

B

X=1, Y=1

C

X=1, Y=0

D

X=0, Y=0

Text Solution

Verified by Experts

The correct Answer is:
C

The truth table cab be written as

Hence, X = 1, Y =0 gives output R = 1
