Josh creates a query that uses an expression to calculate a summarized value. He wants to filter the results of the query using a specific date, so he types, "31-Oct-12" in the Criteria row of the Date column. Which best describes Josh’s error?

a. Filters cannot be created using specific dates, only date ranges.
b. A pound symbol must appear before 31 and after 12 in the date.
c. The date must be entered in the Total row of the Date column.
d. Dates cannot be entered using the day-month-year format.
