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.
DELETE is used to remove data from a database, not retrieve it.
ALTER is used to modify the structure of a database object, such as a table or column, not to retrieve data.
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.
IMPORT is used to bring data into a database from an external source, not to retrieve existing data from within it.
