Which scenario represents a violation of equal protection laws?

The scenario that represents a violation of equal protection laws involves restrictions on selling to nonminorities. Equal protection laws are designed to ensure that all individuals are treated equally under the law and are protected from discrimination based on characteristics such as race, religion, ethnicity, or national origin.

In this case, imposing restrictions that prevent the sale of property to individuals based solely on their minority status is discriminatory and violates the principle of equal treatment. Such actions undermine the foundational tenets of equal housing opportunities and the fair housing laws that prevent practices which discriminate against individuals based on their race or ethnicity.

In contrast, the other scenarios—providing equal housing opportunities, offering housing benefits to all, and permitting all applicants to compete equally—are in alignment with equal protection laws as they promote fairness and equal treatment for all individuals, regardless of their minority status.
