Location 2 represents Avanti, located in the Malwa region of central India, corresponding to modern Ujjain and surrounding areas in Madhya Pradesh. Its capital was Ujjain.

Incorrect Options
Option A is incorrect. While Matsya and Anga are correctly identified for locations 1 and 4, location 2 is Avanti, not Cedi. Cedi was located in the Bundelkhand region. Similarly, location 3 is Vatsa, not Kosala. Kosala was situated in the Awadh region of Uttar Pradesh.
Option B is incorrect. Location 1 is Matsya, not Surasena. Surasena was centered around Mathura. Location 4 is Anga, not Magadha. Magadha was located in southern Bihar, with its capital at Rajagriha and later Pataliputra.
Option D is incorrect. None of the Mahajanapadas listed in this option (Surasena, Cedi, Kosala, Magadha) correctly correspond to the marked locations 1, 2, 3, and 4 respectively on the map.
