Explanation
The correct option is B: 2006.
Chapter XXIA of the Code of Criminal Procedure (CrPC) deals with plea bargaining, which is a process of negotiation between the accused and the prosecution, where the accused agrees to plead guilty in exchange for some concessions from the prosecution.
This chapter was added to the CrPC by the Criminal Procedure (Amendment) Act 2006, which came into effect on the 5th of July 2006. The objective of this amendment was to reduce the backlog of pending cases in courts and encourage speedy disposal of criminal cases.
