a. tension
b. shear
c. uniform
d. compression

Tension stress of a fault occurs when slabs of rock are pulled apart from each other.

Option A

Explanation:

Rocks and Scattered stones that are being pulled apart from each other is known as tension stress, which is also called as extension. The tension causes the stones to elongate or fall apart. It is the most important type of stress occurring at various board boundaries.  

The stress is shear when the forces operate in parallel, but in opposite directions. It is the element of stresses vertical to a given surface, such as surface cracking due to forces acting to the surface or external forces transferred by the surrounding rock.
