Final answer:
The U.S. Supreme Court addressed same-sex marriage, equal protection under the law, and due process in its Obergefell v. Hodges opinion.
Step-by-step explanation:
In its Obergefell v. Hodges opinion, the U.S. Supreme Court addressed all of the above issues: same-sex marriage, equal protection under the law, and due process.
The court held that the due process clause of the 14th Amendment guarantees that the government will recognize same-sex marriages formed in other states. Additionally, the court found that the equal protection clause requires states to issue marriage licenses to same-sex couples if they also issue them to other types of couples. The ruling established same-sex marriage as a constitutional right across the United States.
