If product is oxy acid with $-ous$ suffix

(B) The reaction is: $Cl_2O + H_2O \longrightarrow 2HClO$.In $Cl_2O$,the oxidation state of $Cl$ is $+1$.In the product $HClO$ (hypochlorous acid),the oxidation state of $Cl$ is $+1$.Since the oxidation state remains the same,the product is an oxyacid of chlorine with the $-ous$ suffix (hypochlorous acid).Therefore,the correct option is $B$.
