A reverse fault is a type of dip-slip fault where the hanging wall moves up relative to the footwall at an angle greater than 45 degrees. A thrust fault is a type of reverse fault where the fault angle is even lower, typically less than 30 degrees. Therefore, the only option where the hanging wall moves up at an angle less than 45 degrees is a thrust fault.
