The correct chronological order of leaders is:
C. Gilgamesh, Sargon I, Cyrus the Great, Alexander the Great
The other options are not in the correct chronological order:
A. Alexander the Great, Xerxes I, Sargon II, Hammurabi - This order jumps around in time, with Alexander the Great being the most recent and Hammurabi being one of the earliest.
B. Tiglath-Piliser I, Hammurabi, Naram-Sin, Gilgamesh - This order also jumps around in time, with Hammurabi being much earlier than the other three leaders.
D. Hammurabi, Alexander the Great, Sargon II, Naram-Sin - This order is also not in chronological order, with Alexander the Great being much later than Hammurabi and the other two leaders being from different time periods.
