Answer:
C. The close arrangement of two elements to enhance description.
Step-by-step explanation:
Juxtaposition is the act of putting or placing two elements together, side by side, with the intention of compare/ contrast, to bring their similarities or differences. It is most commonly used to make comparisons.
This literary element enables writers or an author to put things together for easy comparison without the need to use metaphors or similes. Thus, juxtaposition is the close arrangement of two elements for enhanced description or comparison.
