The correct option is "1 and 2 only" because, in India's parliamentary system, members of the Cabinet must be drawn from the Parliament, ensuring that the executive is directly accountable to the legislature (Statement 1). Furthermore, ministers retain their positions as long as they have the confidence of the majority in the Lok Sabha, which embodies the principle of collective responsibility (Statement 2). Conversely, Statement 3 is incorrect, as the Cabinet is headed by the Prime Minister (the Head of Government), not the Head of State, who is the President. This distinction underscores the parliamentary principle of ministerial responsibility and the separation of ceremonial and executive roles.
