If product is oxy acid with $-ic$ suffix

(A) The reaction is $H_3PO_5 + H_2O \longrightarrow H_3PO_4 + H_2O_2$.In the product $H_3PO_4$ (phosphoric acid),the phosphorus atom is in its $+5$ oxidation state.The suffix $-ic$ is used for the acid where the central atom is in its higher oxidation state (e.g.,phosphoric acid).Since $H_3PO_4$ is an oxy acid with an $-ic$ suffix,option $A$ is correct.
