Is it legal or illegal to tell an individual that an apartment has been rented when it is actually available?

The correct choice is that it is illegal to falsely inform an individual that an apartment has been rented when it is actually available. This practice falls under discriminatory housing practices and can violate fair housing laws. Misrepresenting the availability of housing can be seen as a deceptive act that is meant to manipulate potential renters, potentially leading to allegations of discrimination or fraud. Real estate professionals are required to deal honestly and transparently with clients and potential tenants. Upholding integrity in advertising and leasing practices is essential to ensure fair treatment and equal opportunities in housing.

Regarding the other options, legality can often depend on specific circumstances or local laws, but the general principle governing fair housing is that misleading individuals about property availability is unacceptable. Therefore, while certain local laws may have nuances, the overarching legality remains consistent, emphasizing the importance of honesty in real estate transactions.
