c. to exaggerate
Hyperbole is used to exaggerate a thought or idea. It often makes the tone humorous or overly dramatic. It's important to be careful when using hyperbole in writing because it can also make the speaker seem unreliable since a hyperbole is not a complete truth. A few examples of everyday hyperboles are: My homework is going to take forever. I'm so hungry, I could eat a cow. I'm so embarrassed, I could die.
The correct answer is C. Simile.
Explanation
A simile is the name of a rhetorical figure that consists of highlighting the similarity between one element and another, to attribute to the first characteristics of the second. According to this definition in the sentence "And closest contact with the human is like a lantern shining in the night" because it highlights the similarity between two events such as human contact and a lantern shining at night by using the word like. Therefore, the correct answer is C. Simile.
I don't see any underlined words in the sentence. However, I'll just post my answer based on my understanding.
