The default storage engine used is . . . . . . . .

Solution(By Examveda Team)

EXAMPLE: This option is incorrect. EXAMPLE is not a default storage engine in MySQL. It is merely an example storage engine provided for testing and educational purposes.
ARCHIVE: This option is incorrect. While ARCHIVE is a storage engine in MySQL, it is not the default storage engine used when one is not explicitly specified.
MyISAM: This is the correct option. In most MySQL installations, the default storage engine used when a storage engine is not specified explicitly is MyISAM. However, it's important to note that this may vary depending on the MySQL version and configuration.
NDB: This option is incorrect. NDB (MySQL Cluster) is another storage engine provided by MySQL, but it is not the default storage engine used when one is not specified.

Therefore, the default storage engine used in MySQL is Option C: MyISAM.
