Option 1 -> Places Kannauj (1540) before Chausa (1539), which is incorrect chronologically.
Option 2 -> Places Haldighati (1576) first, which is the latest battle among all four, making this sequence incorrect.
Option 3 -> Places Second Battle of Panipat (1556) first, which occurred after both Chausa and Kannauj, making this incorrect.
Option 4 -> Follows the correct chronological sequence: Chausa (1539) → Kannauj (1540) → Second Battle of Panipat (1556) → Haldighati (1576).
Hence, Option 4: (C), (A), (D), (B) -> The Battle of Chausa (1539) and Battle of Kannauj (1540) were both fought between Sher Shah Suri and Humayun, resulting in Humayun's defeat and exile. The Second Battle of Panipat (1556) marked Akbar's consolidation of Mughal power by defeating Hemu. The Battle of Haldighati (1576) was fought between Akbar's forces and Maharana Pratap of Mewar -> correct
