B The executive branch is responsible for execution of laws and daily administration.

Governments can be classified as either parliamentary or presidential. The legislature is the law-making arm of the government while the executive is responsible for the implementation of the laws and daily administration of the country. In a parliamentary form of government, the executive body is responsible to the legislative body while in a presidential form of government, like in the case of USA, both the bodies are independent of each other.
