The method getElementsByTagName("h1") returns all elements with the tag name "h1". This includes all h1 elements in the entire document. Option A would only return the element with the ID "h1" (which may not even exist), Option C would only return elements with a class of "h1" (again, there may not be any such elements), and Option D is not a valid method for selecting elements by tag name. Therefore, the best choice is B.
