<em>B. 7.</em>
Explanation:
The Seventh Amendment was added in 1791 and is part of the Bill of Rights. This amendment is known for protecting the right to having a trial by jury.
This also makes it illegal to discriminate in the workplace. You can not turn down somebody because of their religious beliefs, or give raises based on that kind of criteria. Employers have to accept their employee's religious beliefs without discrimination or putting other religious beliefs onto them.
