Final answer:
The earliest date is Mar. 14, 1388.
Step-by-step explanation:
The earliest date from the given options is Mar. 14, 1388. To determine the earliest date, we need to compare the months first, then the days, and finally the years. In this case, March comes before May and February. Within March, the 14th is earlier than the 24th and the 12th. Finally, 1388 is earlier than both 1397 and 1398. Therefore, Mar. 14, 1388 is the earliest date.
