Explanation

To have a file holding a list, you need to: (1) identify which records belong in the list, and (2) identify the structure (name, width, type) of fields in each record. Option (3) about identifying a file in a record doesn't make semantic sense in this context. The correct answer combines (1) and (2) as both are necessary.
