The correct answer is C) The word in their own language for German was Deutsch, and it was misunderstood by English speakers.
German immigrants were referred to as the Pennsylvania Dutch because the word in their own language for German was Deutsch, and it was misunderstood by English speakers. In the beginning, it is obvious to think that American people already settled in the Pennsylvanian territories had confused the word "Deutsch" with the word "Dutch." Historians supposed that Germans corrected the Americans once and twice, but in the end, they accepted being called Pennsylvania Dutch instead of Pennsylvania Germans.
