The correct answer is: the executive remains responsible to the legislature.

In a parliamentary form of government, the executive branch (the Prime Minister/Cabinet) is drawn from and directly accountable to the legislative branch (Parliament). This continuous responsibility ensures that the executive must retain the trust and confidence of the legislature to stay in power.

Key Reasons & Advantages:

1. Accountability: Members of Parliament can question, critique, and hold the executive accountable for its actions, policies, and governance through mechanisms like Question Hour, debates, and motions of no-confidence.
2. Prevention of Authoritarianism: Because the executive cannot function independently without legislative backing, power remains collective and balanced, preventing dictatorship or arbitrary decision-making.
3. Harmony: Unlike the presidential system where friction between the executive and legislative branches can cause political gridlock, the parliamentary system fosters cooperation since the executive is part of the legislature.
