Answer:
The metaphor "Thomas Baker stepped on your foot with his dirty boots and turned your sneaker into a construction site" is a figure of speech that compares the damage done to the boy's sneaker by Thomas Baker's dirty boots to a construction site. The correct answer to your question would be:
OB. Thomas Baker is a bully who steps on people's shoes for no reason.
The metaphor suggests that Thomas Baker is intentionally causing harm to the boy's sneaker, similar to how a bully intentionally causes harm to others. The comparison to a construction site emphasizes the extent of the damage done to the sneaker, implying that it is now unusable or in need of extensive repairs.
