What constitutes a first violation of Federal Fair Housing Laws?

The correct choice is discrimination based on race or color, as it directly violates the Federal Fair Housing Laws. These laws, enacted primarily through the Fair Housing Act of 1968, aim to eliminate discrimination in housing based on protected characteristics, which include race, color, national origin, religion, sex, familial status, and disability. A first violation is recognized when a party engages in discriminatory practices that adversely affect individuals or groups based on these characteristics.

This choice underscores the gravity of discriminatory acts and reinforces the idea that such behavior not only undermines fairness in housing but is also subject to legal consequences. Recognizing and addressing discrimination is essential for promoting equity and inclusion in housing opportunities for all individuals.
