Solution

The correct option is D $p O H$ of $b$ increases and $A$ decreases
$N a O H$ is a strong base and acetic acid is a weak acid. Their salt will be basic in nature. Sample $A$ which is a strong acid will take the salt towards acidic nature decreasing the pH and hence increases the $p O H$ .
Whereas sample $B$ which is a strong base will take the sample towards basic nature and the $p H$ of the sample $B$ increases resulting in the decrease of $p O H$ .
