Who mainly has the responsibility to implement a policy?

Correct answer: Executive

The executive is the branch of government that carries out laws and policy decisions. It includes the political executive, such as ministers, and the permanent executive, such as civil servants and other officials. After a policy has been approved through the proper government process, executive departments arrange the programmes, issue directions, manage resources, and implement the decision in practice. It is therefore mainly responsible for putting policy into operation.

Option A is correct because implementation is a central function of the executive. The opposition can question and scrutinise government actions but does not normally implement the government's policy. Voters choose representatives and can influence public decisions, while the media informs and discusses them; neither is the main implementing authority. Thus the executive turns an approved policy from a decision into practical administrative action.
