Answer:
a. nothing.
Step-by-step explanation:
Based on the scenario being described it can be said that in a contributory negligence jurisdiction, the plaintiffs could recover nothing. This is because a contributory negligence jurisdiction focuses on the plaintiff's failure to exercise reasonable care for their safety and therefore reducing the degree of the claim, which since in this case Precision Craft is not at fault at all then Stan's heirs would recover nothing in this case since the fault was on Stan's negligence.
