Answer:
D. The right to a lawyer; it allows a defendant to always be able to defend themselves in a criminal case.
Step-by-step explanation:
The famous Supreme Court case Gideon v. Wainright in 1963 was a case regarding a convict Clarence Earl Gideon, who had no legal representation and his pleas to be given a lawyer by the government. The ruling was in favor of Gideon and asked the state to provide a lawyer for the defendant.
According to the 14th Amendment of the US Constitution, every citizen has the right to equal protection under the law. And the 6th Amendment also states that criminal defendants have the right to get representation even if they cannot afford one. So, in respect to these two amendments, the Gideon v. Wainright case touched both issues and thus, gave the defendant the right to be represented by a lawyer and also be given the chance to defend himself in any criminal case.
Thus, the correct answer is option D.
