Answer:
Imagery
Step-by-step explanation:
You haven't highlighted the underlined words, but I'll assume that they are scuttled off sideways. Either way, the correct answer is imagery. Imagery is descriptive and figurative language used by writers and poets to help us create a visual representation of what they've written. For example, the verb to scuttle is very specific and often used to describe the way crabs move. It means to move quickly, with small, short steps, especially in order to escape. The use of this word makes it easy to imagine a crab moving sideways in this manner.
