7.
The answer is: D
Explanation
The correct option is D: (a) and (b).
The Code of Criminal Procedure 1973 provides the procedure for the implementation of the criminal justice system and the mechanism for the investigation and trial of offences. The Code specifies how the substantive criminal law, which defines crimes and prescribes punishments, is to be enforced by the police, courts, and other authorities. The Code also lays down the rights and duties of the accused, the victims, the witnesses, the prosecutors, and the judges in relation to criminal cases. The Code does not deal with civil matters, which are governed by a separate set of laws and procedures.
