Answer:
Step-by-step explanation:
The dual of a function means replace AND with OR and replace OR with AND.
XOR gate of A , B is

So, Dual of A XOR B is ( replace AND with OR and OR with AND)
Complement of A XOR B is
(In finding compliment AND becomes OR and OR becomes AND ).
By inter changing the above product of terms
Complement of

So, Dual of A XOR B = Complement of A XOR B.
