(A) The complete hydrolysis of $PCl_{5}$ proceeds as follows:$PCl_{5} + 4H_{2}O \rightarrow H_{3}PO_{4} + 5HCl$The final product is phosphoric acid,$H_{3}PO_{4}$.In the structure of $H_{3}PO_{4}$,there are three $P-OH$ bonds.Since hydrogen atoms attached to oxygen atoms in $P-OH$ groups are acidic and ionisable,all three hydrogen atoms in $H_{3}PO_{4}$ are ionisable.Therefore,the number of non-ionisable hydrogen atoms is $0$.

The number of non-ionisable hydrogen atoms present in the final product obtained from the complete hydrolysis of $PCl_{5}$ is :
