Which of the following statements about section 190 of the Bharatiya Nyaya Sanhita, 2023 is incorrect?

If an offence is committed by any member in prosecution of the unlawful assembly's common object, every person who is a member at that time is guilty of that offence.

The alternative statutory limb covers an offence committed by a member which the assembly's members knew was likely to be committed in prosecution of that object.

To attract the offence under section 190 BNS, some overt act on the part of a member of the unlawful assembly is necessary to render him liable under section 190 BNS.

The person made liable under section 190 must be a member of the unlawful assembly at the time the offence is committed.
