Answer:
The correct answer is 4. A metaphor.
Explanation:
Metaphors are words, linguistic expressions or various forms of imagery that are used with transferred meaning. That is, one writes or talks about one thing to express another thing. A metaphor is a comparison in which the comparative word is not included.   Metaphors are very common in everyday expression in all languages, that transfers the meaning of the original name to another object.
