Which of the following quotes is attributed to Winston Churchill?

Winston Churchill was a master orator, and his speeches during World War II rallied the British people during their darkest hours. He served as Prime Minister twice, but it's his wartime leadership that cemented his place in history. The quote, "Never in the field of human conflict was so much owed by so many to so few," refers to the brave pilots of the Royal Air Force during the Battle of Britain in 1940, when they defended the country against the German Luftwaffe. His famous declaration, "I have nothing to offer but blood, toil, tears and sweat," was delivered in his first speech to Parliament as Prime Minister in May 1940, setting a tone of grim determination. And the defiant statement, "We shall never surrender," encapsulates the spirit of resistance he instilled in the nation. All three of these quotes are iconic examples of Churchill's powerful rhetoric and are widely attributed to him, making "All of these" the correct answer.
