C)At 30 km/h, as a recommendation, for the stretch of road where the danger persists.Correct
The lower sign recommends driving at an approximate speed of 30 km/h. When this information sign is placed below a danger warning sign, as in the case of this question, the recommendation applies to the stretch of road where the danger exists. Therefore, it is recommended to drive at 30 km/h for as long as the danger from an area frequented by children persists.
