Answer:
b. means that, even assuming the defendant is negligent, if the plaintiff is even slightly negligent, the plaintiff recovers nothing.
Step-by-step explanation:
Contributive negligence is a tort in law that allows the defender in a case to completely prevent a plaintiff from getting any recovery in a case.
This occurs if the defender can prove the plaintiff is negligent resulting in their own injury. That is self injury.
On the other hand comparative negligence allows the plaintiff recover a certain percentage in case of negligence that affects himself. For example if plaintiff was 10% negligent then they lose 10% of the amount they were to recover.
So contributory negligence means that, even assuming the defendant is negligent, if the plaintiff is even slightly negligent, the plaintiff recovers nothing.
