Quizplus · Accepted Answer

AutoNumber data type is the best choice for primary keys as it provides a unique and sequential number for each record, and avoids the possibility of duplicate or missing values. Customer name, birthday, and number data type may contain duplicates or have different formats, which can make it difficult to ensure a unique primary key.
