सही विकल्प विकल्प 2 है।

संकल्पना:

डी मॉर्गन का नियम समीकरण हैं:

(P.Q)'  →  P' + Q'

(P+Q)' →  P' . Q'

व्याख्या:

( A  ⊕  B )' =  ( A'B + AB' )'  

= ( A'B )' . ( AB' )'     [डी मॉर्गन के नियम का उपयोग करके]

= ( A'' + B' ) . ( A' + B'' )

= ( A + B' ) . ( A' + B )

= ( A.A' ) + ( A.B ) +  ( A'B' ) + ( B'.B ) = ( A.B) + (A'B')

= A' ⊕ B
