बूले के व्यंजक $x \leftrightarrow \sim y$ का निषेधन निम्न में से किस के समतुल्य है ?

A

$(\sim x \wedge y) \vee(\sim x \wedge \sim y)$

B

$(x \wedge \sim y) \vee(\sim x \wedge y)$

C

$(x \wedge y) \vee(\sim x \wedge \sim y)$

D

$(x \wedge y) \wedge(\sim x \vee \sim y)$

(JEE MAIN-2020)

Solution

$p \leftrightarrow q \equiv( p \rightarrow q ) \wedge( q \rightarrow p )$

$x \leftrightarrow \sim y \equiv( x \rightarrow \sim y ) \wedge(\sim y \rightarrow x )$

$\because( p \rightarrow q \equiv \sim p \vee q )$

$x \leftrightarrow \sim y \equiv(\sim x \vee \sim y ) \wedge( y \vee x )$

$\sim( x \leftrightarrow \sim y ) \equiv( x \wedge y ) \vee(\sim x \wedge \sim y )$
