A. accountable to parliament
B. responsible for its own actions
C. headed by a prime minister
D. the head of state that controls the government
Correct Answer: Option A
A. accountable to parliament
Explanation
A parliamentary system is a system of democratic governance of a state where the executive derives its democratic legitimacy from its ability to command the confidence of the legislature, typically a parliament, and is also held accountable to that parliament. In a parliamentary system, the head of state is usually a person distinct from the head of government. This is in contrast to a presidential system, where the head of state often is also the head of government and, most importantly, the executive does not derive its democratic legitimacy from the legislature.
