Which of the following represents a type of discrimination prohibited by the Fair Housing Act?

The type of discrimination that is prohibited by the Fair Housing Act is based on certain protected classes, which include race, color, national origin, sex, disability, and familial status. Charging different prices based on race directly contravenes the Fair Housing Act's mandate to ensure that individuals are treated equally in housing transactions, regardless of their racial background.

The Fair Housing Act seeks to eliminate discrimination that creates barriers for individuals in accessing housing. Pricing that reflects racial discrimination not only harms affected individuals but also undermines the principle of equal opportunity in housing.

In contrast, refusal to rent based on age, discrimination related to credit history, or limiting access based on gender do not fall under the protected classes defined in the Fair Housing Act. While those practices may involve forms of discrimination, they are not explicitly prohibited by the Act as it currently stands.
