Final answer:
The correct literary device for words like "Bang!", "hiss", "drip", and "whoosh" is onomatopoeia, as they mimic the sounds they represent.
Step-by-step explanation:
The literary device exemplified by the words "Bang!", "hiss", "drip", and "whoosh" is onomatopoeia. Onomatopoeia refers to words that sound like the object or action they are intending to describe. These words phonetically imitate, resemble or suggest the sound that they describe. For example, the word "drip" sounds like the actual sound of liquid falling drop by drop.
This is different from other options such as alliteration, which involves the repetition of the initial consonant sounds in a sequence of words, a metaphor, where one thing is described as being the same as another, and a simile, which compares two things using "like" or "as". Therefore, the correct answer is b. Onomatopoeia.
