Solution

The correct option is B III only
To form a basic solution $K_{3} P O_{4}$ will hydrolyze in water.
$K_{3} P O_{4}$ is a salt of strong base ( $K O H$ ) and weak acid $H_{3} P O_{4}$
KOH completely dissociates in solution to provide hydroxide ions.
$H_{3} P O_{4}$ partly dissociates in solution to provide hydrogen ions.
Hence, hydroxide ion concentration is smaller than hydrogen ion concentration. Hence, the solution is basic.
