Which amendment guarantees basic rights to individuals accused of crimes?

The 5th Amendment is indeed the key constitutional provision that guarantees basic rights to individuals accused of crimes. This amendment encompasses several important protections, including the right against self-incrimination, which means individuals cannot be compelled to testify against themselves in a criminal case. Additionally, the amendment ensures that no person is subject to double jeopardy, which protects individuals from being tried for the same crime twice, and it mandates due process of law, ensuring fair legal proceedings before an individual is deprived of life, liberty, or property.

This combination of protections plays a crucial role in safeguarding the rights of the accused and upholding the principle of fairness in the judicial process. As such, it directly addresses the rights of those who are facing criminal charges, making it the correct answer in identifying the amendment that guarantees these fundamental rights.
