Keeping in Mind Any Applicable Defenses, Which of the Following

Keeping in mind any applicable defenses, which of the following examples best shows negligence per se?

A) Myron parks his truck in a no-parking zone. Dixie parks her motorcycle behind it at a parking meter. The truck jumps out of gear and rolls over the motorcycle.
B) As Allison crosses her neighbor's land to reach a fishing stream, she falls into a clearly visible abandoned well. A state statute requires landowners to seal such wells.
C) Bubba owns a restaurant. One of his customers is injured when a grease fire breaks out on the grill. The local health code requires restaurants to clean food preparation surfaces daily. Bubba's grill had not been cleaned for several weeks.
D) Daniel Li stores a can of lighter fluid on his apartment balcony. This violates his lease. The can overheats and explodes, burning down the building.
