Some literary devices here are similes and metaphors. I'm sorry for only providing 2, if I can spot a third I will let you know. An example of a simile in the poem is "When harsh words cut like a knife". Comparison using terms such as "like" is a clear demonstration of a simile. An example of a metaphor in the text is "Hiding in the Internet's shadows". Notice how hiding in the shadows of the internet is not possible in a literal sense, but lacks the usage of terminology like "like" or "such as" "as a" that a simile would provide. Good luck!
The correct answer among all the other choices is A.) attributes. This element is analogous to "sweet herbs" in this analogy from Little Women by Louisa May Alcott. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
