The correct answer is - A. shear.
The stress types, compression, tension, ans shear, are the three responsible for the formation of most of the landscape that we see on our planet. They are all triggered by the activity of the inner layers of our planet which dictate the power, pressure, temperature, movement, destruction, construction, on the surface of the Earth. These stresses can be vertical stresses, sideway stresses, or diagonal stresses, and that all helps into the creation of different types of relief forms with different characteristics.
