What regulatory action strengthened enforcement against redlining by expanding protected classes?

• A. Create HOLC maps
• B. Prohibit redlining entirely
• C. Amend the Fair Housing Act to add protected classes and strengthen enforcement
• D. Establish a national rent control policy

Answer: (C)

Expanding protected classes in the Fair Housing Act strengthens enforcement against redlining. Redlining is the practice of denying or limiting housing-related services to people based on race, national origin, or other group characteristics. By adding more groups to the list of protected classes and enhancing enforcement tools, the law covers a broader range of discriminatory behaviors and gives regulators and courts clearer authority to pursue violations, impose penalties, and provide remedies for affected individuals. This direct expansion of protection and enforcement capacity makes it the most effective regulatory action for curbing redlining. The other options either relate to historical practices, aim to prohibit something outright that isn’t currently enforced, or address a policy area unrelated to fair housing enforcement.
