Answer:
The offense that refers to a protection first established by Magna Carta is:
a) For depriving us in many cases, of the benefits of Trial by Jury.
Magna Carta, which was signed by King John of England in 1215, established the principle that no person should be deprived of life, liberty, or property without due process of law. One of the key features of due process is the right to a trial by jury, which is designed to ensure that individuals are not subject to arbitrary or unjust decisions by the government. The Declaration of Independence lists the British king's deprivation of the benefits of trial by jury as one of the offenses committed against the American colonists, which suggests that the colonists believed that this protection was being violated by the British government.
