What type of stress occurs when one plate pushes against another?
a) compression
b) faulting
c) shearing
d) tension

C). Shearing.

Explanation:

Stress is described as the intense pressure exercised by a physical object and the object's response to the adjustment.

As per the question, 'shearing' is the type of stress that occurs when one plate pushes against another as it involves an exterior force applied on the object(pushing of plate against another) is parallel to the 'plane'(plate) it pushes and it functions to deform/shear the object without altering its volume. Thus, option C is the correct answer.
