Which statement best describes hydrostatic pressure with respect to velocity?

Hydrostatic pressure depends on depth and density but not on velocity.

Hydrostatic pressure is the pressure in a fluid due to the weight of the fluid above a point. In a fluid at rest, it increases with depth according to p = ρ g h, showing dependence on density and depth, not on how fast the fluid is moving. If the fluid is in motion, there is dynamic pressure related to velocity, but that is a separate component from hydrostatic pressure. Viscosity deals with internal friction, and color has no role in pressure.

Hydrostatic pressure increases with velocity.

Hydrostatic pressure depends on viscosity.

Hydrostatic pressure depends on color.
