The correct option is A To command the people
The State is a body of government which runs a country. It is present to implement the rules and law among the citizen's of the state. In the process of overlooking administration, functions such as serving, protection, healthcare are carried out by the State. So, options A, C and D reflect duty of a State. Whereas, commanding people in option B is quality of dictatorship or authoritarian regime and not a duty of State.
