The correct answer is option 3, which correctly matches the listed articles of the Indian Constitution to their corresponding provisions.

In option 3:

- Article 14 is correctly matched with 2 - The state shall not deny to any person equality before the law or the equal protection of laws within the territory of India.

- Article 15 is correctly matched with 1 - The State shall not discriminate against any citizen on grounds only of religion, race, caste, sex, place of birth or any of them.

- Article 16 is correctly matched with 4 - There shall be equality of opportunity for all citizens in matters relating to employment or appointment to any office under the State.

- Article 17 is correctly matched with 3 - `Untouchability` is abolished and its practice in any form is forbidden.

The other options incorrectly match the articles to their provisions, hence they are incorrect.

So, by understanding the core principles of each article, one can correctly match them with their appropriate provision, which is accurately done in option 3.
