The correct answer is (b), The Public Prosecutor.
The Public Prosecutor is the only person who can withdraw a prosecution at any time before the judgment is pronounced. This is because the Public Prosecutor is the representative of the State in criminal proceedings. The State has the power to prosecute offenders in order to protect the public from crime. However, the State also has the power to exercise its discretion not to prosecute in certain cases. This discretion is usually exercised by the Public Prosecutor.
The aggrieved person, i.e., the person who has suffered the injury or loss as a result of the crime, does not have the power to withdraw a prosecution. This is because the prosecution is not brought in the name of the aggrieved person, but in the name of the State. The aggrieved person may, however, make a request to the Public Prosecutor to withdraw the prosecution. The Public Prosecutor may or may not agree to the request.
The writer of the First Information Report (FIR) is also not a person who can withdraw a prosecution. The FIR is a document that is filed with the police when a crime is reported. The FIR is not a prosecution. The prosecution is a process that is initiated by the State through the Public Prosecutor.
In conclusion, the only person who can withdraw a prosecution at any time before the judgment is pronounced is the Public Prosecutor.
