The correct action to use to populate a database with large amounts of data from an external source is B. IMPORT.

An IMPORT operation is used to bring data from an external source into a database. This is typically used when the data already exists in a file or in another database and needs to be added to the current database. The IMPORT operation can be used to add data to an existing table or to create a new table.

On the other hand, the EXPORT operation is used to extract data from a database and save it to an external file or another database. This is typically used when you want to create a backup of the data or transfer it to another location.

SELECT and ALTER are SQL commands used to retrieve and modify data in a database respectively. SELECT is used to retrieve data from a table or multiple tables based on specified criteria, while ALTER is used to modify the structure of a table, such as adding or removing columns.

Therefore, the correct action to use to populate a database with large amounts of data from an external source is IMPORT.
