Explanation:

Answer: (c). data dictionary and transaction log

Two important files required for database operations are data dictionary and transaction log. A data dictionary, or metadata repository, as defined in the IBM Dictionary of Computing, is a "centralized repository of information about data such as meaning, relationships to other data, origin, usage, and format". Oracle defines it as a collection of tables with metadata and a transaction log is a file – integral part of every SQL Server database. It contains log records produced during the logging process in a SQL Server database.
