Final answer:
To maintain parallel structure, option A (guiding) should be used as it consistently uses the gerund form to modify the doer, ensuring that the sentence maintains a clear and uniform construction.
Step-by-step explanation:
When revising sentences to create parallel structure, it is essential to ensure that elements of the sentence that are meant to be analogous are presented in the same grammatical form. In this case, to maintain parallelism and clarity, option A (guiding) matches the doer and action sentence pattern effectively. Therefore, the revision should read as follows:

This option uses the gerund 'guiding' consistently to modify the doer, ensuring that the underlined section flows smoothly with the rest of the sentence, adhering to parallel structure.
