Article 368 of the Indian Constitution empowers the Parliament to amend the Constitution and lays down the procedure for such amendments.
This article gives the Parliament the authority to modify, add to, or repeal any part of the Constitution, subject to certain limitations laid down by the Supreme Court in landmark cases such as the Kesavananda Bharati case.
The amendment process is significant because it ensures the Constitution remains a living document, adaptable to changing times and needs, while also protecting its basic structure.
Now let's review the other options:
(B) Article 103 deals with the powers and privileges of Parliament members, not amendments.
(C) Article 129 pertains to the Supreme Court’s power as a court of record, unrelated to amendments.
(D) Article 234 relates to the appointment of district judges, again not relevant here.
Hence, the correct and relevant article for constitutional amendments is Article 368.
