What is the importance of the ministerial oath in the system of governance?

Correct answer: It binds a minister to duties such as loyalty to the Constitution and maintaining secrecy

Direct answer: A is correct. Before entering office, a minister takes an oath or affirmation prescribed by the Constitution. The oath expresses commitment to bear true faith and allegiance to the Constitution, faithfully discharge the duties of office and, where applicable, maintain the secrecy of information received as a minister. It reminds the minister that office is a public trust, not personal property, and that decisions must be taken within constitutional limits. B is wrong because taking the oath does not change a minister into a judicial officer. C is wrong because a minister is part of the political executive, not a permanent civil servant. D is plainly unrelated: the oath has no power to abolish the Lok Sabha. The oath alone does not guarantee good conduct, but it establishes a formal constitutional responsibility. Memory cue: oath means constitutional duty, faithful service and secrecy—not extra personal power.
