Explanation
The defining characteristic and main advantage of the parliamentary form of government is the principle of collective responsibility of the executive to the legislature. In this system, the government (executive) is formed from the legislature, and it remains in power only as long as it enjoys the confidence of the legislature. This accountability ensures that the executive is responsive to the will of the elected representatives and, through them, to the people. Options A, B, and D are not the primary distinguishing advantages; for example, the executive and legislature do not work independently (A), continuity can be an issue (B), and changes can occur without elections through no-confidence motions (D).
