The question asks which of three described features is NOT actually stated in Section 63(4) of the Bharatiya Sakshya Adhiniyam, 2023 regarding the certificate needed to authenticate electronic evidence. Each option needs to be checked against what the provision and its Schedule actually require.
Because all three specific features are indeed found in Section 63(4), none of them qualifies as something "not stated," making the residual option correct.
Therefore, the correct answer is None of the above.
