Which act was significant for setting standards against discrimination in real estate transactions?

The Fair Housing Act is the correct choice as it was specifically designed to eliminate discrimination in housing-related transactions and to promote equal housing opportunities. The act, passed in 1968, makes it illegal to refuse to rent or sell a home to a person because of race, color, national origin, religion, sex, familial status, or disability. It laid out the framework for the enforcement of these rights and has been crucial in shaping housing policies, ensuring individuals have the right to purchase or rent regardless of their background.

While the Civil Rights Act of 1968 does encompass some aspects related to housing and discrimination, the Fair Housing Act is the specific legislation that directly addresses housing discrimination in a comprehensive manner. Other legislation, such as the Americans with Disabilities Act, focuses more broadly on accessibility and accommodations for individuals with disabilities in various public and private sectors, and the Housing and Urban Development Act deals with broader aspects of urban development and does not specifically target discrimination in real estate transactions.
