Section 8 IEA makes 'motive, preparation and previous or subsequent conduct' of any party:

1. Section 8 IEA makes the following relevant: (i) any fact which shows or constitutes a MOTIVE or PREPARATION for any fact in issue or relevant fact; (ii) the CONDUCT of any party to any proceeding or person against whom an offence is the subject of investigation, in reference to such proceeding/offence/fact, whether previous or subsequent, provided such conduct influences or is influenced by any fact in issue or relevant fact. 2. Motive is the inducement to act; preparation includes prior steps; conduct includes acts before, during or after the fact in issue. 3. Explanation 2: when conduct of any person is relevant, any statement made to him or in his presence which affects such conduct is relevant. 4. Hence option C captures the section accurately. _Source: Indian Penal Code 1860 / Code of Criminal Procedure 1973 / Indian Evidence Act 1872 (Bare Acts, indiacode.nic.in) — Indian Evidence Act, Section 8_
