Correct Response: D. Since all three words must appear in a title, this search will return the fewest results compared with just one or two of the words appearing. A is incorrect because only one of the three search terms must be in the title, so many more results will be found. B is incorrect because either the first two words must both appear or the third word must appear, but not all three, so more results will appear. C is incorrect because the third word and either the first or second words must appear, but not all three, so more results will appear.
