2. Understand the purpose of each clause in the context of data handling and backup.

Relevant Concepts

1. BACKUP: This command is explicitly designed to create a backup of a database or data.
2. CREATE: This command is used to create new database objects but does not pertain to backing up data.
3. SELECT INTO: This command can be used to create a backup copy of a table by selecting data into a new table, but it is not the primary way to backup a database.
4. UNION: This command is used to combine the results of two or more SELECT queries and does not pertain to backing up data.

Analysis and Detail

• The most straightforward and common clause used specifically for backing up data is the BACKUP clause. While SELECT INTO can be used to create copies of data, it does not serve the same purpose as BACKUP in a database system.

Verify and Summarize

• After analyzing the options, the BACKUP clause is the correct choice for backing up data. While there may be other ways to backup data indirectly, BACKUP is the most appropriate answer.

Final Answer

The correct answer is: a. BACKUP.
