The correct option is:
Both have explicitly different punishments based on social class.
The Code of Hammurabi explicitly defined different punishments for individuals based on their social status, with harsher penalties for lower classes compared to those for higher classes. In contrast, modern American law is designed to be impartial and aims to treat all individuals equally, regardless of their social class. However, in practice, there can still be disparities in how laws are applied, but the intent of modern law is to be blind to social class.
