<span>Jim stops frozen in his tracks. His reaction is probably that he thinks he may have entered the wrong apartment by mistake. He doesn't even recognize his wife at first. He thinks he is looking at a stranger, and he doesn't understand what this strange woman is doing in his apartment and what has become of Della.
I hope this helps you</span>
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.
