B Correct answer
Explanation

When the Gregorian calendar was adopted in 1582, 10 days were skipped to realign the calendar with the solar year. October 4, 1582 was followed directly by October 15, 1582 - so October 5-14, 1582 never existed in countries that adopted the calendar immediately (Italy, Poland, Spain, Portugal). September 14, 1852 existed, and February 29 existed in both 1804 and 1904 (leap years).
