Isaac was injured in an accident that was caused by Jason's negligent behavior. Isaac sued Jason, seeking compensatory damages. When the trial concluded, Isaac was awarded NO damages. As it turned out, Isaac sued Jason in the State of Missibama, one of the few states that still recognized an old common law rule that completely barred recovery for a plaintiff when the defendant could show the plaintiff's own negligent actions were a factor in causing the plaintiff's injuries or losses. Isaac did prove that Jason was negligent, but Jason effectively invoked this rule to avoid being held liable for Isaac's injury. Which of the following statements correctly characterizes this?
a. Jason used The State of Missibama's common law rule for lack of personal jurisdiction over negligence per se when a plaintiff has assumed the risk of the activity to cut off his liability for Isaac's claim.
b. Isaac's recovery for his tort claim was blocked because Jason proved that he had defense immunity.
c. Isaac filed suit alleging the wrong tort claim, so Jason proved the court did not have jurisdiction.
d. Isaac's recovery for his tort claim was drastically reduced because Jason proved that, comparatively, Isaac was 30% responsible for his own injuries.
e. Jason used the defense known as contributory negligence to completely block Isaac's recovery for his negligence claim.
