The correct answer is option 2, which states that all three statements are correct. Let`s examine each statement individually:

Statement 1: The procedure for amendment to the Constitution is provided in Article 368. This statement is correct. Article 368 of the Indian Constitution outlines the procedure for amending the Constitution. It sets out the different ways in which amendments can be proposed and ratified.

Statement 2: A Bill to amend the Constitution can be introduced in either House of the Parliament. This statement is also correct. There is no restriction on which House of Parliament can introduce a Bill to amend the Constitution. Both the Lok Sabha and the Rajya Sabha have the authority to initiate amendments.

Statement 3: The special procedure in Article 368 vests constituent powers upon ordinary legislation. This statement is correct. The special procedure outlined in Article 368 gives the power to amend the Constitution exclusively to Parliament. It distinguishes between ordinary legislation and constitutional amendments, vesting the authority to make changes to the Constitution in Parliament.

In conclusion, all three statements provided in option 2 are correct.
