Answer:
A. Metaphor
Step-by-step explanation:
A metaphor is a figure of speech that refers to the change, the transfer of a name or word from one term to another based on an obvious or hidden analogy.
This figure of speech can describe an object or action but in a way opposite from true meaning. That description can help the writer to explain an idea.
In this example, metaphorically is used feeling loneliness to be compared with something that can be broken. Using this metaphor writer wants to show the greatness of a pain that someone is feeling.
