Answer:
The answer is A. oxymoron.
Step-by-step explanation:
This literary figure consists of the use of two words that have different meanings but they combine together to create a literary effect. In this excerpt, Romeo uses oxymorons as Brawling love or loving hate. Here we can see that these two words have different meanings and connotations. He used this figure to represent the bitter love he had for Rosaline. He is constantly comparing love with sad or tragic words as "Feather of lead, bright smoke, cold fire, and sick health". This figure of speech is used to show the duality in this case of love, that can be beautiful but also chaotic and painful.
