✅ Correct Answer: (D)
Database-file-record-fteldsbyte- bit
Explanation: Data is organized in a data storage hierarchy of increasingly complex levels: bits, bytes, fields, records, files, and databases. Data are logically organized into: I Bits (characters) : a bit is the smallest unit of data representation (0 or 1); I Byte : a unit of digital information that most commonly consists of 8 bits; I Field : a field consists of a grouping of characters; I Record : record consists of fields, with each field describing an attribute of the entity; I File : a group of related records; I Database : anintegrated collection of logically related records or files
