Explanation: The correct answer is (c) Character, field, record, file, database. Explanation: A character is the smallest unit of data that can be processed, such as a letter or a number. A field is a collection of characters that represents an attribute of an entity, such as a person's name or address. A record is a collection of fields that represents a complete set of information about an entity, such as a customer or an order. A file is a collection of records, typically of the same type, stored in a single unit, such as a text file or a spreadsheet. A database is a collection of related files that are organized in a way that facilitates efficient retrieval of information. Therefore, the order from smallest to largest common data elements is character, field, record, file, database.
