what are you trying to tell
The correct sentence is C, because 'driven' is the past participle, part of the present perfect tense. Present participle would be 'driving', it has -ing form, whereas B is not correct because 'helped' is just past, not a past participle.
Please Post the story So I can answer your question and put who character S is.
