You are underway on course 315°T at 14 knots. The current is 135°T at 1.9 knots. What is the speed being made good?

Correct Answer: Option D — 12.1 knots

The current (135°T) is directly opposing the ship's course (315°T). The Speed Made Good is the ship's speed (14 knots) minus the drift (1.9 knots). This simple subtraction confirms the vessel is making 12.1 knots over the ground, as per standard piloting calculations.
