Correct Answer: Option C — 00h 02m on the 6th
Crossing the 180th meridian from west to east advances the calendar date by one full day while local mean time advances continuously. Adding 6 minutes to 23h 56m on the 4th yields 00h 02m, and crossing the International Date Line shifts the date to the 6th.
