To identify the term for a voluntary statement acknowledging guilt:
1. Under the Indian Evidence Act, 1872, a confession is a voluntary statement made by an accused person admitting guilt of the crime charged.
2. Acceptance, statement, and consent do not specifically denote this legal admission of guilt.
3. A confession is admissible in court if made voluntarily and without coercion.
Therefore, the correct answer is (4) Confession.
