ASA-Congruence: If any two angles and the side included between the angles of one triangle are equivalnet to the corresponding two angles and side included between the angles of a second triangle, then the two triangles are congruent.
In the given diagram you have a side and a angle marked as equal, then to have a congruence by ASA the diagram needs to mark that the angle N and angle Q (angles that make the side marked as equal be the included side) are equal:
Answer: tick marks showing that angle N is congruent to angle Q (option D)
