Explanation:

Let’s analyze each option:

- Option 1: Articles 328 and 329

- These articles relate to the power of the legislature of a state to make provisions with respect to elections and bar courts from interfering in electoral matters. They do not relate to Scheduled Castes or Tribes.

-

- Option 2: Articles 331 and 332

- Article 331: Representation of the Anglo-Indian community in the House of the People.

- Article 332: Reservation of seats for Scheduled Castes and Scheduled Tribes in the Legislative Assemblies.

- These focus on representation, not on specifying the castes/tribes.

- Option 3: Articles 341 and 342

- Article 341: Empowers the President to specify the Scheduled Castes by public notification.

- Article 342: Empowers the President to specify the Scheduled Tribes by public notification.

- This pair is the correct answer.

- Option 4: Articles 343 and 344

- These articles relate to the official language of the Union and formation of official language commission. Not relevant here.

Correct Answer:

- Option 3: Articles 341 and 342

- These articles directly deal with the Presidential notification for specifying Scheduled Castes and Scheduled Tribes.
