Correct answer: C. It would force the other vehicle to suddenly slow or change direction causing danger.
When overtaking make sure the road ahead is clear so you have enough distance to overtake and get back to your own side of the road without forcing any other road user to adjust speed or direction. When you are well past the vehicle, check the mirrors, signal and gradually return to the original lane, making sure not to cut across the vehicle you have passed.
