Actually, sentence number 2 uses the past form of an irregular verb. In this sentence, the verb "seen" is the past participle form of the irregular verb "see." The past form of "see" is "saw," but in this sentence, the present perfect tense is being used with the auxiliary verb "has" and the past participle "seen." So, the correct answer is sentence number 2.
