10. in which one of the following examples is the date written correctly?
a. monday, november 12, 2004
b. wednesday, aug. 6 2003
c. wed., 10-23, 1997
d. monday, november, 12, 2004

When writing dates in long format, there should be a comma after the day of the week and a comma after the specific date. You should also note that the whole words should be used, especially when you aim for the formal tone of writing. So looking at your choices, you can rule out B, C, and D. 

The correct answer would be A. Monday, November 12, 2004.
