Answer :

Lieutenant Frederic Henry, from the novel "A Farewell to Arms" by Ernest Hemingway, is: c) German. In the novel, Lieutenant Henry is actually an American serving as an ambulance driver in the Italian army during World War I. Despite his American nationality, he is often mistakenly identified as being of German descent due to his last name, Henry. This confusion arises because Henry is not a typical American name, leading some characters in the novel to assume he is German. However, Lieutenant Henry is indeed American, not German.
