A vessel is steaming on course 090°T at 10 knots. A current is setting 180°T at 2 knots. Which term correctly describes the direction 180°T in this scenario?

Why A is correct

Bowditch Ch. 23 §2302 defines set as the direction toward which the current is flowing. Drift is the speed of the current (2 knots in this case). Course made good is the resultant track over ground after combining the vessel's water track with the current vector.
