Final answer:
Shear stress occurs at convergent boundaries when tectonic plates collide, causing fault lines and mountain formation.
Step-by-step explanation:
Shear is a type of stress that occurs when two or more forces act in opposite directions parallel to a surface. In the context of the given options, the situation that involves shear is option E: Convergent boundaries. When two tectonic plates collide, they can cause shear stress along the boundary, resulting in fault lines and the formation of mountains. This is often associated with intense earthquakes and the movement of rock layers sliding past each other.
