C
It's a transform fault because the Pacific Plate and the North American Plate are moving sideways against each other and the fault extends about 800 miles.
Step-by-step explanation:
Occasionally, because the fault is rugged and snaky, the plates get stuck against each other in their movement causing a build-up of energy at the point where they are stuck. When such a point gets unreleased abruptly, the built-up energy is suddenly released causing massive earthquakes. Smaller earthquakes do frequently occur (compared to big ones) as the friction between the two plates causes smaller stick-release points.
