The correct answer is D. It has protected civil rights using the Fourteenth Amendment and other laws.
Explanation
In the events presented in the questions, situations of discrimination against different minority communities such as ethnic groups, racial groups, and homosexual groups are exposed. This discriminatory conduct is classified as illegal because the Fourteenth Amendment of the United States established a clause that deals with equal treatment of all people in all states of the country, so treating them in a differential or discriminatory manner is considered illegal. Additionally, in the second case (the case of racial discrimination on the bus), reference is made to the Interstate Commerce Law, which prohibits discrimination in interstate transportation. Therefore, the correct answer is D. It has protected civil rights using the Fourteenth Amendment and other laws.
The supremacy clause of the U.S. Constitution has supported the "<span>national government's sovereignty over matters related to citizen health care and education" since these can technically be decided at the state level as well, as opposed to interstate commerce and foreign policy, which can only be handled at the federal level. </span>
