All of the following are protected classes EXCEPT:

• A. Illegal drug sellers
• B. Race
• C. Color
• D. National origin

Answer: (A)

Protected classes in housing law are attributes people cannot be discriminated against for, such as race, color, and national origin. Race and color describe inherent identity, and national origin refers to where someone comes from. Illegal drug sellers, however, do not describe a protected characteristic—the Fair Housing Act targets discrimination based on identity, not occupation or illegal activity. It’s true the law does protect individuals with disabilities (including those with a history of addiction or who are in recovery), but it does not shield someone who is currently engaging in illegal drug use. Because of that, the one that doesn’t fit as a protected class is the description of illegal drug sellers.
