The Microsoft Access wildcards are ____ and ____ .

Option A: asterisk (); percent sign (%) - This option is incorrect. While the asterisk () is a wildcard character in Microsoft Access (and SQL generally for SELECT statements), the percent sign (%) is used in SQL for pattern matching, not specifically as a wildcard in Microsoft Access.
Option B: percent sign (%); underscore () - This option is correct. In Microsoft Access, the percent sign (%) is used as a wildcard for matching zero or more characters, and the underscore () is used as a wildcard for matching a single character.
Option C: underscore (); question mark (?) - The underscore () and question mark (?) are not commonly used as wildcards in Microsoft Access. This option is incorrect.
Option D: question mark (?); asterisk () - The question mark (?) and asterisk () are not typically used as wildcards in Microsoft Access. This option is incorrect.
Conclusion:
In Microsoft Access, the wildcards are Option B: percent sign (%) and underscore (_). These characters are used for pattern matching in queries to match specific text patterns within data fields. Therefore, the correct answer is Option B.
