B Correct answer
Explanation

"U-boat" comes from German "Unterseeboot" (undersea boat). German U-boats were used extensively in both World Wars, particularly in WWI and WWII for unrestricted submarine warfare. The term specifically refers to German submarines, not American, French, or British vessels. The US called them "submarines" or "subs," the UK "subs," and France "sous-marins."
