A)120 km/h.

C)90 km/h.Correct
The sign in the image indicates the start of a multi-lane road and, therefore, the point from which the special traffic rules for this type of road apply. The general maximum speed for cars on a road that is not a motorway or dual carriageway is 90 km/h, so the overtaking speed will also be 90 km/h.
