Why Darcy's law does not incorporate velocity head ?

One of the options below is the answer:.

(a) Pressure head is always very high.

(b) Darcy's law does consider velocity head, just like Darcy's earlier pipe flow equation that he developed with Weisbach,

(c)Flow velocity in porous matrix is negligible compared to the effect of hydraulic gradient.

(d)There is no friction loss None of the answers apply.
