Answer:
The example of figurative language in the given options is:
d. Dillon lit up like a firefly when Dad walked in the door.
Explanation:
Figurative language uses words or expressions that have a different meaning than their literal interpretation. In this example, the phrase "lit up like a firefly" is a simile, which is a type of figurative language. It compares Dillon's reaction to that of a firefly lighting up, emphasizing his excitement or happiness when his dad walked in the door. The comparison adds a vivid and imaginative element to the statement, going beyond a literal description of Dillon's reaction.
