Solution

The correct option is D all of these
Ionisation of phosphoric acid is as shown below:
$1) H_{2} O + H_{3} {P O}_{4} \to H_{3} O^{+} + H_{2} {P O}_{4}^{-} 2) H_{2} O + H_{2} {P O}_{4}^{-} \to H_{3} O^{+} + H {P O}_{4}^{2 -} 3) H_{2} O + H {P O}_{4}^{2 -} \to H_{3} O^{+} + P O_{4}^{3 -}$
Hence, option D is the correct answer.
