In the context of the Bharatiya Sakshya Adhiniyam, 2023, which of the following is the best evidence?

Direct evidence under section 55 of the Bharatiya Sakshya Adhiniyam, 2023 (formerly section 60 of the Indian Evidence Act, 1872) is the evidence of a person who saw, heard or otherwise perceived the fact himself, and it is regarded as the best evidence of that fact, so the answer is "Direct evidence". Hearsay is generally excluded, circumstantial evidence proves a fact only by inference, and documentary evidence concerns the contents of documents rather than the fact perceived.
