Final answer:
Option (1) An allusion is an indirect reference in a literary work to other works or ideas, such as in the play 'Hamlet' where Greek mythology is referenced. Allusion is the correct answer to the question, which asks about such references in literature.
Step-by-step explanation:
The allusion is a reference in a literary work to the Bible, mythology, history, or other literature, which is indirect or implied rather than directly stated. For example, when in Shakespeare's Hamlet, the title character refers to his father as "Hyperion" and his uncle Claudius as a "satyr," he is making allusions to Greek mythology, which the audience is expected to recognize.
Unlike an allusion, a metaphor is a direct comparison saying something is something else, as in "My love, you are a rose," and a simile makes a comparison using "like" or "as," for example, "My darling, you are like a rose." Meanwhile, personification involves giving human characteristics to non-human entities. In the context of the given choices, (1) Allusion is the correct answer to the question.
