The correct answer is: a) Nagaland Police
The Nagaland Police is the state police force of Nagaland, India. It is headed by the Director General of Police (DGP), who is appointed by the Governor of Nagaland on the advice of the state government. The DGP is assisted by a number of Additional Directors General of Police (ADGPs), Deputy Inspectors General of Police (DIGs), Superintendents of Police (SPs), and Deputy Superintendents of Police (DSPs).
The Nagaland Police is responsible for maintaining law and order in the state, and for investigating and prosecuting criminal cases. It also provides security to VIPs and other important persons, and enforces traffic regulations.
The Nagaland Police is a well-trained and professional force, and has a good record of maintaining law and order in the state. It has also been successful in combating crime and terrorism.
The other options are incorrect because:
- The Indian Army is a federal force that is responsible for defending the country from external aggression. It is not responsible for maintaining law and order within the country.
- The Central Reserve Police Force (CRPF) is a paramilitary force that is responsible for maintaining law and order in disturbed areas. It is not responsible for maintaining law and order in Nagaland, which is not a disturbed area.
- The Ministry of Home Affairs (MHA) is a central government ministry that is responsible for internal security. It does not have any direct role in maintaining law and order in Nagaland.
