ACD.
B is a scalar with size and no direction
Of course, ACD has its own size. The direction a is vertical and downward, the direction C is from the starting point to the stop point, and the direction D is not easy to say. Anyway, it is determined by the willing speed direction and the direction after acceleration, which is similar to the understanding of the resultant force of the two forces
