Final answer:
The Fair Housing Act protects against housing discrimination on the basis of race, color, national origin, religion, sex, familial status, and disability, not gender, which is protected under Title VII in the context of employment.
Step-by-step explanation:
The Fair Housing Act is a law that prohibits discrimination in housing on several bases. It is important to note that this Act is different from Title VII of the Civil Rights Act, which prohibits discrimination in employment on the basis of race, gender, national origin, religion, or sexual orientation. The Fair Housing Act specifically prohibits discrimination in the sale, rental, and financing of dwellings, and in other housing-related transactions, based on race, color, national origin, religion, sex, familial status, and disability. Therefore, the correct answer to the question 'The fair housing act protects against discrimination based on all the following, except:' would be 'B) Gender,' since gender is not a category protected under the Fair Housing Act.
