Consider the following statements :

$A$ : Rishi is a judge.

$B$ : Rishi is honest.

$C$ : Rishi is not arrogant.

The negation of the statement "if Rishi is a judge and he is not arrogant, then he is honest" is

A

$B \rightarrow( A \vee C )$

B

$(\sim B ) \wedge( A \wedge C )$

C

$B \rightarrow((\sim A ) \vee(\sim C ))$

D

$B \rightarrow( A \wedge C )$

(JEE MAIN-2022)

Solution

$\sim(( A \wedge C ) \rightarrow B )$

$\sim(\sim( A \wedge C ) \vee B )$

Using De-Morgan's law

$( A \wedge C ) \wedge(\sim B )$
