The correct answer is B. Prevent unfair or deceptive bussines practice.
Consumer protection laws are designed to secure the consumer's rights. They are also in charge of ensuring fair trade and well informed marketplaces. The laws prevent fraud and unfair practices.

I believe that what can be inferred from these lines from the play Everyman is that B. only a person's good deeds remain with him or her in the afterlife.
Everything else is fleeting and disappears, but your good deeds will forever be remembered.
In case something important or bad happens
