Concept:Liquid pressure depends on the vertical height of liquid and its density, not on the shape or surface area of the liquid.Explanation:Pressure at a point in a liquid is given by $P = h \rho g$.Here, $h$ is the depth below the liquid surface, and $\rho$ is the density of the liquid.So, pressure increases with deeper depth and with higher liquid density.The surface area of the liquid does not appear in the formula.Thus, pressure is independent of the surface area of the liquid.Therefore, pressure depends only on statements I and II.Answer:A. I and II only.
