Concept:In a parliamentary system, the executive branch is drawn from and directly accountable to the legislature, not independently elected by the people.
Explanation:The main distinguishing feature is the relationship between the executive and the legislature.
The executive, led by the Prime Minister, is usually chosen from the majority party in parliament.
This means the executive must enjoy the confidence or support of the legislature to remain in power.
If the legislature withdraws its support, the executive can be removed, often through a vote of no confidence.
Thus, the executive is effectively appointed by and from the legislature, making the legislature central to forming government.
Options A, B, and C do not describe a defining feature of the parliamentary system.
Answer:D. The executive is appointed by the legislature.
