Which of the following is true about the nature of a metaphor?

A metaphor is a figure of speech that makes an implied comparison between two unlike things by stating that one thing is another. This is done without using the words "like" or "as," which are typically reserved for similes. The strength of a metaphor lies in its ability to evoke imagery and emotional connections by suggesting that two different elements share common characteristics.

In contrast, the other options include elements commonly associated with similes or other descriptive techniques. Metaphors inherently rely on indirect comparison; they imply relationships and qualities rather than defining things in a straightforward manner. The indirect nature of metaphor allows for deeper interpretation and understanding, encouraging readers or listeners to engage with the language creatively. This is what makes option C the accurate statement regarding the nature of a metaphor.
