I think that the correct answer is D. Interpretations are often quite different.
An allusion is a figure of speech that refers to a place, person, or event. This can be real or imaginary and may make reference to anything, including fiction, folklore, historical events, or religious manuscripts. The reference can be direct or may be inferred, and can broaden the reader's understanding.
Allusions engage the reader and will often help the reader remember the message or theme of the passage.
