If A is the area of the surface, x is the depth of its C.G. from the surface of the water and ω is the density of water, then

[A]. total pressure on the surface is equal to ω x
[B]. depth of the point at which total pressure acts is equal to its moment of inertia divided by A x
[C]. depth of the centre of pressure is 2/3H vertically below the surface
[D]. all the above.

Only C is correct.
As total pressure= ρ*g*h'*A.
And centre of pressure = (Icg/Ah')+h'.
