Answer:
B. It is most effective when one begins with a weak punishment and gradually works up to a stronger punishment.
Explanation:
Punishment is most effective when one begins with a weak punishment and gradually works up to a stronger punishment. This means that, if someone were to do something wrong that wasn't a big deal or danger to others, they would most likely not have a bad punishment. However, if someone put anyone in danger, they would get a harsh punishment, to make sure they don't make that mistake again.
