A check digit is a digit that is added to a primary key to help identify data entry errors. It is determined by applying a formula to the numbers in the primary key value. Therefore, option B is the correct answer. Option A (data type) refers to the type of data stored in a field (such as text, number, or date), option C (field size) refers to the maximum number of characters that can be stored in a field, and option D (default value) is the value that is automatically entered in a field if no other value is specified.
