Answer:
C. to convey moral or political messages through the use of symbolism.
Explanation:
A literary device can be defined as any technique used by speakers and authors (writers) to significantly emphasize on their writeups or compositions and express their ideas, opinions or thoughts to the audience.
An allegory can be defined as a literary technique typically used as a symbolic fictional description or narration to express (convey) specific ideas or abstractions that are not explicitly stated in the literary work.
This ultimately implies that, an allegory refers to a symbolic fictional narration where actions, settings, characters, objects, or events are used to convey large-complex ideas that are not explicitly stated.
In this context, the reason which best describes the purpose of an allegory is to convey moral or political messages through the use of symbolism.
A literary symbol can be defined as an object that has one or more figurative meanings rather than just its literal meaning.
In English literature, symbols (symbolism) are used to give a literary work deeper (more) meaning and to convey a larger idea to the audience. Thus, when an object represents or stands for an idea or emotion, it is called a symbol.
In conclusion, symbols comprises of motifs, characters, images, settings etc, that typically represents larger ideas.
