Answer:
D. Allusion
Step-by-step explanation:
An allusion is a literary device that refers to a well-known person, place, event, or work of literature. In the example given, the phrase "modern day Romeo" is an allusion to William Shakespeare's play "Romeo and Juliet", which is a well-known story about two young lovers.
The sentence is saying that the pop star is not like Romeo, who is often romanticized as a tragic hero, but instead, the pop star is only valued for his physical appearance. By using the allusion to "Romeo", the sentence creates a comparison between the pop star and a well-known character to convey the idea that the pop star is not what he is commonly portrayed to be.
