Which of the following can be classified as a discriminatory practice under the Fair Housing Act?

The Fair Housing Act is designed to prohibit discrimination in housing based on specific protected characteristics, including familial status. Refusing to rent to families is a clear violation of this act, as it specifically targets individuals with children and denies them equal housing opportunities based solely on their family status. This practice is considered discriminatory because it creates unequal access to housing based on a person's familial status, which is expressly prohibited under the law.

In contrast, offering different lease terms may not necessarily be classified as discriminatory unless it can be shown that these terms are applied in a manner that adversely affects a protected class. Restricting properties by credit score and limiting access based on income could also be problematic, but they are not inherently discriminatory unless they disproportionately impact individuals based on a protected category. The Fair Housing Act primarily focuses on specific traits such as race, color, national origin, religion, sex, familial status, and disability, and the refusal to rent to families directly contradicts its intent.
