1 kt of current equals how much wind?

The main idea is how drift from current translates into the wind the vessel effectively feels. Apparent wind is shaped by the vessel’s motion through the air, which is influenced by both wind and the water current moving the ship’s position. Even a small current can produce a surprisingly large perceived effect on the vessel’s handling because it changes the speed and direction with which the ship moves through the air. In training contexts, a rough rule of thumb is that 1 knot of current can be treated as a very strong wind in terms of its impact on drift and the heading corrections you’d need, which is why the option representing a large wind value is selected. The other choices describe far smaller wind effects and don’t capture the potential impact a current can have on apparent wind and course when you’re maneuvering.
