Final answer:
The right to be represented by counsel refers to the right to have a C. lawyer. This right is guaranteed by the Sixth Amendment, and was reinforced by the Gideon v. Wainwright case, which mandates that a state must provide a lawyer to those who cannot afford one.
Step-by-step explanation:
All persons have the right to be represented by counsel, also known as a lawyer.
This right is a fundamental aspect of the Sixth Amendment of the U.S. Constitution, which ensures that in all criminal prosecutions, the accused have the right to the Assistance of Counsel for their defense. The landmark case of Gideon v. Wainwright extended this right to require states to provide an attorney for defendants who could not afford one on their own. This ensures that every individual has access to a fair trial, regardless of their financial status.
Therefore, the answer to the question is C. a lawyer.
