For the purposes of the Bharatiya Sakshya Adhiniyam, 2023, who among the following is not an accomplice?

An accomplice is a person who took part in the offence. A trap witness who only helps to expose an offence, a girl who is the victim of rape, and a person who merely saw a murder are not participants, so "All of the given options are correct". Only a true accomplice's evidence attracts the provisions on corroboration in Section 138 and illustration (b) to Section 119 of the Bharatiya Sakshya Adhiniyam, 2023 (formerly Section 133 and illustration (b) to Section 114 of the Indian Evidence Act, 1872); the distinction between a victim or observer and a culpable participant remains important.
