The Literal Grammarian: This crowd insists the answer is “What” because of the classic structure of this wordplay joke. In spoken riddles, it is often presented as: “A man has three daughters… What is the father’s name.” (Using a statement, not a question).
The Practical Thinker: Others argue that because the image explicitly uses a question mark, it must be a question. For this group, the riddle is simply unsolvable with the information provided. The father’s name could be anything from Bob to Bartholomew—the names of his daughters have no logical bearing on his own name.
