Which type of fault is under compression

The correct answer is reverse fault.

Explanation:

The kind of fault witnessed under compression is known as a reverse fault. A reverse fault takes place when two Earth's crust pieces are pushed together. The location at which the collision between the two tectonic plates takes place is called a convergent boundary. When the collision between these two plates takes place, the formation of a nearly vertical fault plane takes place. This segment is called the hanging wall of the fault.
