Explanation:
The 1968 Federal Fair Housing Laws established that it is illegal to discriminate or refuse housing to a person based on race or color; religion; national origin; familial status or age—includes families with children under the age of 18 and pregnant women; disability or handicap, or sex.
Option A would be considered as a violation of the no discrimination based on race stipulation of the law.
Option C would be a violation of the no discrimination based on sex stipulation of the law.
And Option D would be a subtle violation but nonetheless a violation of the no discrimination based on race stipulation.
Option B is the only option that doesn't seem to break any of the stipulations of the 1968 act.
