Answer:

B. Her eyes began to droop, her mind began to wander, and then her limbs softened.

Explanation:

Parallelism refers to the repetition of a chosen grammatical form within a sentence. It uses word, phrases or clauses that are grammatically similar or identical in structure, sound, meaning, or meter, with the purpose of showing that the stated ideas are equally important and to give a natural flow to the piece of writing.

Sentence B uses this method as the clauses " Her eyes began to droop" and "her mind began to wander" have the same grammatical structure.
