Explanation:

- Article 368: Grants power to the Parliament to amend the Constitution. This provision specifies the procedure for amendments, making it clear how various articles including the fundamental rights are to be altered.

This is the correct answer.

- Article 103: Addresses the decision on questions as to disqualifications of members of either House of Parliament. It does not deal with constitutional amendments.

- Article 129: Declares the Supreme Court of India to be a court of record. This has no relation to the amendment of the Constitution.

- Article 234: Concerns the recruitment of persons other than District Judges to the judicial service of a state. This is unrelated to constitutional amendments.
