A base velocity image

The correct answer is d.

Radial velocity image showing blue and green colors to the north and west of the radar and red and yellow colors to the south and east of the radar.

The light shades of green and orange touch the location of the radar. Drawing a line directly from the inbound velocities in green to the outbound velocities in orange at the location of the radar, we can see that the wind must be blowing from the northwest at approximately 20 to 26 knots.
