Final answer:
The correct answer is option C: "and the wife of Percy Shelley," which provides a parallel structure to the sentence by continuing the list of Mary Shelley's roles.
Step-by-step explanation:
The sentence that best correctly completes the sentence with parallel structure is option C: "and the wife of Percy Shelley." Parallel structure, or parallelism, is the repetition of a certain form, which provides balance and clarity in writing. In the given sentence, Mary Shelley is being described by her roles, so the correct completion of the sentence should maintain that same structure.

Together, they lived a life full of passion, scandal, and literary creativity, with close relationships to other influential artists of their time. Mary was the product of two very influential parents, providing her a unique position within the literary and philosophical circles of her day.
