Generally, the DATE is entered in the form

Answer: Option D

Generally, in Disk Operating System (DOS), the date is entered in the form Option D: MM-DD-YY. This format represents the month (MM), day (DD), and year (YY) separated by dashes.

Option A, "DD-YY-MM," is not a standard format used for entering dates in DOS.
Option B, "YY-DD-MM," and Option C, "MM-YY-DD," are also not standard formats used for entering dates in DOS.

Therefore, the correct answer is Option D: MM-DD-YY.
