Option 1 -> Places Ahmad Shah Abdali's victory (1761) before Nadir Shah's invasion (1739), which is chronologically incorrect.
Option 2 -> Correctly sequences: Babur (1526), Sher Shah (1540), Nadir Shah (1739), Ahmad Shah Abdali (1761).
Option 3 -> Places Nadir Shah's invasion (1739) before Sher Shah's victory (1540), which reverses the actual timeline.
Option 4 -> Places Nadir Shah (1739) at the beginning, before even Babur (1526), which is historically inaccurate.
Hence, Option 2: (B), (D), (C), (A) -> The correct chronological sequence is: Babur defeats Ibrahim Lodi at First Battle of Panipat (1526), Sher Shah defeats Humayun (1540), Nadir Shah invades India and sacks Delhi (1739), and Ahmad Shah Abdali defeats Marathas at Third Battle of Panipat (1761) -> correct
