If J refuses to lease an apartment to a man due to previous tenants being women only, which of the following statements is accurate?

The statement recognizing that J is violating the Civil Rights Act due to sex discrimination accurately identifies a situation where gender is used as a basis for denying housing. The Civil Rights Act forbids discrimination in housing based on several protected classes, including sex. By refusing to lease an apartment based on the gender of previous tenants, J is not only discriminating against men but also perpetuating a practice that unfairly limits housing opportunities based on sex. This violates the principles of equal housing opportunity that the Act aims to uphold.

While there may be specific exemptions in certain circumstances regarding housing practices, the situation described does not seem to fit within those exceptions. Additionally, using a licensed broker does not exempt J from violations related to discrimination. The matter of whether the landlord occupies any of the units also does not provide a protective measure against such discrimination under the Civil Rights Act. Thus, the recognition of J's actions as a violation of the Act due to sex discrimination is indeed accurate.
