The correct answer to this question is option 3: Matsya, Avanti, Vatsa, Anga. Each of these names corresponds to one of the sixteen great kingdoms, or mahajanapadas, that existed in ancient India.

Starting with option 1, Matsya is correct for A, but Cedi, Kosala, and Anga aren`t the correct placements for B, C, and D respectively, hence it is incorrect.

Option 2 provides the names Surasena, Avanti, Vatsa, and Magadha. While these are all legitimate mahajanapadas, they do not correspond to the correct locations marked A, B, C, and D on the map.

Option 3, the correct answer, pairs each letter with the accurate mahajanapada. Matsya corresponds to A, Avanti to B, Vatsa to C, and Anga to D.

Finally, option 4, like option 2, accurately names mahajanapadas, but fails to assign them the correct locations. Therefore, it is incorrect.

This final review should help the student understand why option 3 is the correct answer.
