in which of the following sentences is the underlined word a past participle
A) she would (like) to join us.
B) We (helped) Joan to pack her things.
C) Jenna has (driven) this route multiple times.
D) I was (working) overtime for about six months
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.
