Answer:
B. When they arrived in America, they denied religious freedom to those in their communities.
Explanation:
Irony is a rhetorical term used when what appears on the surface is contradictory to what really happens or what is expected. In other words, it means when the exact opposite happens, contrary to what had been said or expected.
The Puritans were a group of Protestants who had decided to flee England because of their disagreement with the Church of England's certain similarities or infusion of Catholic practices. In search of religious practice, they arrived in America to freely enjoy and follow their beliefs. But what is ironic is that they did not in fact, have any freedom. On the contrary, they based religious beliefs into their society and way of living, and even drove out those immigrants who do not comply with their 'ways'.
They 'escaped' England to freely practice their religion but refused to give the same liberty to the other immigrants who arrive in America.
Thus, the correct answer is option B.
