According to the 5th Amendment, what is self-incrimination?

Self-incrimination, as defined by the 5th Amendment, refers specifically to the constitutional protection against being compelled to provide testimony or evidence that could lead to one's own criminal prosecution. This principle ensures that individuals cannot be forced to testify against themselves in a legal proceeding, thus safeguarding the right to remain silent and avoid self-incrimination.

The other choices do not pertain directly to the concept of self-incrimination. Being arrested without a warrant relates to the protections against unreasonable searches and seizures, which is addressed by the 4th Amendment. Improper seizure pertains to that same amendment. Denial of legal representation involves the right to counsel, which is protected under the 6th Amendment. Therefore, the specific focus on being compelled to testify against oneself makes the selected answer contextually and legally accurate regarding the 5th Amendment's intent and protections.
