Which type of fault occurs when rock is subjected to this type of stress?

hanging
normal
reverse
strike-slip

c reverse

Explanation:

A reverse force results from the compression of two plates. The compressional stresses leads to the collision or pushing of two rock plates or slabs into each other.  so the collapsing rock slabs are almost vertical but slightly tilted towards the left at the middle length. The foot wall and hanging wall move opposite to each other. Generally it takes place at tectonic plate boundaries.  

so

option C is correct

a. i. only is correct.
