Question

which of the following shows the correct use of a comma? december, 7, 1941 december, 7 1941 december 7, 1941

Explanation:

In date formatting, when writing a date in the month - day - year format (e.g., December 7, 1941), we use a comma to separate the day from the year. In the first option "December, 7, 1941", there is an incorrect comma after the month. The second option "December, 7 1941" is missing the comma between the day and the year and also has an incorrect comma after the month. The third option "December 7, 1941" follows the correct rule of using a comma between the day (7) and the year (1941) and no unnecessary comma after the month.

Answer:

December 7, 1941 (the third option in the list of date - formatted options)
