I would say (A) simile.
- A simile uses "like" or "as" to compare two things.
- Imagery is when the author uses highly descriptive and vivid language to provide an image that the reader can visualize, helping them to understand the text.
- Personification is when non-human objects are given human characteristics.
- A metaphor is a non-literal comparison of two things without the use of "like" or "as".
