The correct option is "1 and 3 only," as it reflects the provisions that safeguard the autonomy of the Supreme Court of India effectively. Statement 1 is correct because the process of appointing Supreme Court judges requires the President to consult the Chief Justice of India, ensuring judicial input in the appointment process and enhancing independence. Statement 3 is accurate since the salaries of Supreme Court judges are paid from the Consolidated Fund of India, which protects their financial independence from legislative control. Statements 2 and 4 are incorrect—judges can be removed only through a parliamentary process, not by the Chief Justice alone, and appointments of court staff require the approval of the Chief Justice but are not solely made by the government.
