Answer:
The word 'Boom' is an example of onomatopoeia as it imitates the sound it represents, fitting the criteria of sounding like the object it is intended to describe.
Step-by-step explanation:
The word that best shows onomatopoeia among the choices given is 'Boom'. Onomatopoeia refers to words that mimic the sounds they describe, and 'Boom' phonetically imitates the sound it represents, which could be the sound of a car engine or a similar loud, explosive noise.
When considering examples of onomatopoeia, it is important to think about how the words relate to the sounds they stand for. In the context provided, words like 'shush', 'bang', 'thud', and 'hiss' are also examples because they audibly resemble the noises they denote. Hence, 'Boom' fits this definition as it sounds like an echoing or resonant sound that one might associate with an engine's operation or a sudden, loud effect.
