PLEASE GIVE THE CORRECT ANSWER
For option (c)
( (0 XOR 1) XOR (0 XOR 1)' XOR 0)'
= (1 XOR 0 XOR 0)'
=0
@Anu007 clearly output is zero for option A
For option (A)
( (1 XOR 1) XOR (1 XOR 1)' XOR 0)'
= (0 XOR 1 XOR 0)'
so option (A) wrong
Why this wrong.
ExNor has property when even number of 0 then output is 1.
@ Anu007 because last circuit is EX-NOR complement of EX-OR , complement of 1 = 0

here we r considreing last gate like this...(a xor b xor c)' not (a Xnor b Xnor c)
EX-OR gate is the odd number of 1's detector whereas EX-NOR gate is even number of 1's detector. EX-OR gate gives output 1 if a number of 1's in the input is odd. EX-NOR gate gives output 1 if a number of 1's in the input is even.
EX-OR gate is the odd number of 1's detector whereas EX-NOR gate is even number of 1's detector.
EX-OR gate gives output 1 if a number of 1's in the input is odd.
EX-NOR gate gives output 1 if a number of 1's in the input is even.
