A "lookup" routine validates an entry by searching for the same data in a file or database table. This is a common practice in data validation where the input data is checked against existing data sources to ensure accuracy and prevent duplicates. Choice A, "validating," is too general and doesn't specify the method of validation. Choice B, "redundancy," refers to having duplicate data for backup purposes and is not related to data validation. Choice D, "normalizing," is the process of organizing data in a database to eliminate redundancy and improve efficiency, but it is not directly related to data validation.
