Which of the following statements is correct under Section 136 of the Code on Social Security, 2020?

Section 136(3) of the Code on Social Security, 2020 (formerly section 11(2) of the Payment of Gratuity Act, 1972) bars any court inferior to a Metropolitan Magistrate or a Judicial Magistrate of the first class from trying offences punishable under Chapter XII, so a second class Magistrate cannot try them. Under section 136(1), cognizance is taken only on a complaint by an aggrieved person or the notified officer, not on a police report, and section 136(4) expressly allows a single complaint by more than one aggrieved person where they are aggrieved by the same or a similar offence.
