Question

did the ruling of loving v. virginia accomplish?
ruled that the \separate but equal\ clause, which legalized the segregation of schools, was unconstitutional
determined that a state does not have the right to tax a federal bank operating within that states jurisdiction
helped uphold the rights for all accused and stated that those who cannot afford their own representation will be granted free legal representation in a court of law
decided a law that criminalized interracial marriage unconstitutional

Explanation:

The Loving v. Virginia case was about challenging laws that banned interracial marriage. The Supreme Court's ruling in this case declared such laws (that criminalized interracial marriage) to be unconstitutional, which matches the description in this option. The first option is about Brown v. Board of Education (school segregation), the second is about McCulloch v. Maryland (state taxing federal bank), and the third is about Gideon v. Wainwright (right to counsel for the accused).

Answer:

The option "deemed a law that criminalized interracial marriage unconstitutional" (the fourth option, assuming the options are presented in the order as given in the text)
