For answer  A 

At night or in reduced visibility conditions, the drivers of motor vehicles, agricultural or forestry tractors and trams that approach an intersection not controlled by traffic lights or by a traffic police officer are obliged to signal by alternating the low beam with the high beam. But in the situation in which from the opposite direction another vehicle moves in compliance with the traffic rules at a distance less than 200 m, this type of signalling can no longer be performed, because in this way you dazzle with the light of the headlights the driver of the vehicle that approaches.

For answers  B  and  C 

The use of the high beam (long beam) is prohibited when from the opposite direction a vehicle approaches at a distance less than 200 meters. Thus, when encountering the vehicles that move in compliance with the traffic rules from the opposite direction or at the signalling of the drivers of motor vehicles who have engaged in a dangerous overtaking, the repeated change of the high beam with the low beam is prohibited.

The correct answer is: A

The correct use of the lighting and signalling system --> Road Code - The technical condition of the vehicles and the lighting and luminous signalling system

(3) At night or in reduced visibility conditions the drivers of motor vehicles, agricultural or forestry tractors and trams that approach an intersection not controlled by traffic lights or by traffic police officers are obliged to signal by alternating the low beam with the high beam if they do not violate thus the provisions of paragraph (2).
