Which of the following is an example of a legal right granted to all people in the United States?

The choice of freedom of religion serves as a foundational legal right granted to all individuals in the United States, protected under the First Amendment of the Constitution. This amendment ensures that citizens have the freedom to practice their religion without interference from the government, as well as the right to abstain from religion altogether. The principle of religious freedom is critical in a diverse society, allowing for different beliefs and practices without fear of oppression or discrimination from the state or other entities.

While the other options represent important rights and protections, they may not be universally recognized or as explicitly stated in the Constitution. For instance, protection from discrimination may be established by various federal laws, but it does not hold the same constitutional status as the freedom of religion. The right to bear arms is also a recognized right, specifically mentioned in the Second Amendment, but it is subject to regulatory measures. The right to privacy in financial matters, while important in specific contexts, does not have the same broad legal standing as the right to freedom of religion, which is a fundamental principle of American democracy.
