A)No, under no circumstances.
B)No, unless overtaking a car.
C)No, unless overtaking two-wheeled motorcycles and without invading the opposite direction.Correct
# Explanation
The no-overtaking prohibition sign allows an important exception: you may overtake two-wheeled motorcycles provided you do not invade the lane in the opposite direction. This exception exists because motorcycles take up less space and overtaking can be done safely within the same lane or with minimal risk. For any other vehicle, the maneuver is completely prohibited.
