In this situation, is the overtaking manoeuvre being performed by the car correct?

A)Yes, because there is no vertical sign prohibiting it.
B)Yes, because it maintains the appropriate clearance and is overtaking a two-wheeled vehicle.
C)No, because it is completely encroaching on the oncoming lane.Correct
A continuous longitudinal line, which delimits lanes or directions of travel, prohibits overtaking when it is necessary to cross it or drive over it.
When it separates the two directions of travel, it also prohibits driving to its left.
Even when overtaking is prohibited, it is permitted to encroach on the lane reserved for oncoming traffic in order to:
- Overtake slow and vulnerable road users (cycles, mopeds, pedestrians, animals and animal-drawn vehicles), when their speed allows the manoeuvre to be carried out without risk.
- Pass obstacles or immobilised vehicles (broken down, involved in an accident, etc.), after making sure there is no danger (if the reason for the immobilisation is imposed by traffic conditions, you may not pass it and must remain behind it).
In the case of this question, it can be seen that it is a motorcycle due to its dimensions, and crossing the continuous line to overtake it is prohibited.
