Executive Accountability to the Legislature

The third statement is correct. The defining advantage of a parliamentary system is the continuous accountability of the executive (Council of Ministers) to the legislature, enforceable via a vote of no confidence. The other statements describe characteristics of a Presidential system: independent branches (Statement 1), policy continuity due to fixed terms (Statement 2), and immunity from legislative removal outside of impeachment/elections (Statement 4).

The Assertion is true; parliamentary systems trade stability for high accountability. Reason 1 correctly supports this by defining the concept of majority confidence. Reason 2 is conceptually false because the core mechanic of the system is that the executive is highly vulnerable to, not immune from, motions of no-confidence.

The third principle is correct. The ability of the legislature to instantly remove the executive (the Prime Minister) via a vote demonstrates collective responsibility and daily accountability, which is the hallmark of the parliamentary system (Nation Y). Executive independence and fixed-term continuity are features of the Presidential system (Nation X).

Only two descriptions are valid (Statements 1 and 3). The executive is dependent on the legislature and can be removed by a no-confidence vote. Statement 2 is false because a parliamentary system cannot guarantee policy continuity; if the legislative majority shifts, the government falls and policies change immediately.
