Three liquids of equal masses are taken in three identical cubical vessels A, B, and C. Their densities are $\rho_{\mathrm{A}}, \rho_{\mathrm{B}}$, and $\rho_{\mathrm{C}}$ respectively. But $\rho_{\mathrm{A}}<\rho_{\mathrm{B}}<\rho_{\mathrm{C}}$. The
force of the cubical vessel is
(a) maximum in vessel A.
(b) the same in all the vessels.
(c) minimum in vessel $\mathrm{C}$.
(d) maximum in vessel $\mathrm{C}$.
