c. If you were to hit it you would knock the boat's brains out.
A hyperbole is an effective device of figurative language that is used for emphasis by making a connection between two seemingly unrelated things. If taken literally, a hyperbole would make no sense. For instance, boats do not have brains; therefore, if taken literally, that makes no sense. However, it is basically understood that for something’s brains to be knocked out, it would have to be quite a powerful hit. Thus, to emphasize/highlight the power of a potential hit to the boat a hyperbole is an effective device here in saying that if the boat were hit, its brains would be knocked out.
