The answer is: D
Explanation
The correct option is D: State Government or Central Government after consultation with the High Court. This is because Section 24 of the Code of Criminal Procedure, 1973 states that:
(1) For every High Court, the Central Government or the State Government shall, after consultation with the High Court, appoint a Public Prosecutor and may also appoint one or more Additional Public Prosecutors, for conducting in such Court, any prosecution, appeal or other proceeding on behalf of the Central Government or State Government, as the case may be.
This means that both the Central Government and the State Government have the power to appoint a Public Prosecutor for the High Court, but they must consult with the High Court before doing so. The other options are incorrect because they either omit the consultation with the High Court or the involvement of the Central Government.
