Why is the office of the Prime Minister in a parliamentary system different from the President’s office in a presidential system?

Correct answer: The Prime Minister depends on the confidence of the legislature

Direct answer: A is correct. In a parliamentary system, the Prime Minister is the leader of the government and normally remains in office only while the ministry has the confidence of the elected legislature, especially the Lok Sabha in India. The executive and legislature are closely connected: ministers are generally members of the legislature or must become members within the permitted period, and they are answerable to it. In a presidential system, the President is usually both head of state and head of government, is elected separately from the legislature and has a more fixed tenure. B is wrong because a Prime Minister does not hold office for life; political support and elections matter. C is wrong because the judiciary does not elect the Prime Minister. D is the opposite of the truth, since parliamentary confidence is central to the office. Memory cue: parliamentary Prime Minister equals legislative confidence; presidential President equals separate election and tenure.
