If surface winds were influenced only by the pressure gradient force and Coriolis force (i.e.without the frictional force)
A)The effects would vary depending on surface texture.
B)there would be no winds at all.
C)winds would flow parallel to isobars and at high rates of speed.
D)winds would flow in a straight line from areas of higher to lower pressure.

Without the frictional force, winds would not experience any drag, and hence, they would flow parallel to isobars and at high rates of speed. This is known as geostrophic flow, where the balance between the pressure gradient force and Coriolis force determines the direction and speed of the wind.
