Answer: B. participate in government
The Magna Carta was signed in June, in the year 1215 by King John, and it clearly states the rights that were available to the people of England. The underlying principle of the Magna Carta is that no one was above the law, no matter who they were. It also stated that everyone was to be treated equally, so both the rich and the poor had equal rights, and were to be treated the same way.
This gave the English people the freedom they needed to involve themselves in activities they normally would not (such as politics and government), and is often used by politicians today, during their campaigns.
