The correct answer is: A. Only I follows
The statement says that the police department has come under a cloud with recent revelations that at least two senior police officials are suspected to have been involved in the illegal sale of a large quantity of weapons from the state police armoury.
Course of action I says that a thorough investigation should be ordered by the State Government to bring out all those who are involved into the illegal sale of arms. This is a valid course of action because it will help to identify and punish those who are responsible for the illegal sale of arms.
Course of action II says that State police armoury should be kept under Central Government’s control. This is not a valid course of action because it does not address the issue of the illegal sale of arms. The illegal sale of arms is a problem that can be solved by taking action against those who are involved in it, not by transferring control of the police armoury to the Central Government.
Therefore, only course of action I follows.
