Explanation:
The bottle fits the riddle because it has a distinct narrow part called a “neck,” which resembles the neck of a living creature. However, unlike creatures, it lacks a “head” at the top. This “neck” is merely a functional shape, designed to make pouring easier, and does not imply any living characteristics.
In simple terms, the “neck” of a bottle serves a purpose without needing a “head,” making it the perfect answer to this riddle.
