The correct answer is C, that is Tension.
Step-by-step explanation:
Stress applied to convergent plate boundary is known as compression convergent boundaries whereas a stress applied to divergent plate boundaries is called as tension divergent plate boundaries. Compressive stress occurs at convergent plate boundaries where two plates advance toward one another. Tensional stress occurs at divergent plate boundaries where two plates are moving far from one another. Shear stress is experienced at change boundaries where two plates are sliding past one another.
