Answer:
Although you have not put the answer options, the movement of the plates in the situation shown above occurs with the approach of their continental plates that collide and bend due to the impact.
Explanation:
The converging movement of the plates indicates that two plates are moving towards each other until they collide. When these two plates are continental, the movement is called continental-continental convergent.
As the two continental plates have the same density, the impact between the two causes them to bend and not sink into each other.
