Why each option

To retrieve data from a relational database, the most common and fundamental action performed is querying, typically using SQL's SELECT statement.

ADELETE

DELETE is used to remove data from a database, not retrieve it.

BALTER

ALTER is used to modify the structure of a database object, such as a table or column, not to retrieve data.

CQUERYCorrect

Querying is the process of retrieving data from a database, most often accomplished in relational databases using the SQL 'SELECT' statement, which specifies the data to be fetched based on certain criteria. This is the primary operation for data retrieval.

DIMPORT

IMPORT is used to bring data into a database from an external source, not to retrieve existing data from within it.
