"Have undergone" vs "have underwent"

The correct phrase is "have undergone." The word "undergone" is the past participle form of the verb "undergo," and when used in the present perfect tense, it should be paired with the auxiliary verb "have." "Have underwent" is incorrect because "underwent" is the simple past form of the verb, not the past participle.
