The correct option is B January 2, 0030 hrs
The Earth takes 24 hours to complete one rotation or to cover 360°of longitudes. This means that the Earth covers 15° of longitudes every hour. Thus, one degree of longitude takes 4 minutes (1 hour = 60 minutes, divided by 15° per hour = 4 minutes per longitude).
Time will be recorded by captain = 23:30 hrs+1 hr=00:30hrs
Time and date will be recorded by the captain of the ship in his diary after one-hour journey from the point of crossing of the meridian will be January 2, 00:30hrs.
