Arnie Negligently Stopped His Car on the Highway

Arnie negligently stopped his car on the highway. Beth, who was driving along, saw Arnie's car in sufficient time to attempt to stop. However, Beth negligently put her foot on the accelerator instead of the brake and ran into Arnie's car. In this case:

A) Arnie's contributory negligence will prevent his recovery from Beth in all jurisdictions.
B) Beth had the last clear chance to avoid the accident and will bear legal responsibility for it.
C) Arnie has assumed the risk of the accident.
D) because both parties were negligent, in a state that follows the pure comparative negligence doctrine, both parties will share the liability for their injuries.
