Consider the following events:
The correct chronological order of the given events is II, IV, III, I.
Options 2, 3, and 4 present incorrect chronological sequences of the events.

The reign of Krishna Deva Raya was subsequent to these events. Therefore, any sequence that deviates from II, IV, III, I is incorrect.
