(B) The initial rate is $r_1 = K[x][y]$.When the volume of the vessel is reduced to $1/4$ of its initial volume $(V_2 = V_1/4)$,the concentration of the reactants increases by a factor of $4$ because concentration $C = n/V$.Therefore,the new concentrations are $[x]_2 = 4[x]$ and $[y]_2 = 4[y]$.The new rate $r_2 = K[x]_2[y]_2 = K(4[x])(4[y]) = 16K[x][y]$.Thus,$r_2 = 16r_1$.The rate of the reaction increases by $16$ times.
