Which keyword is used to begin a query that lists variables returned from an SQL statement?

The keyword that is utilized to start a query for listing variables returned from an SQL statement is SELECT. This keyword is fundamental in SQL (Structured Query Language) as it specifies the columns or fields that you want to retrieve from one or more tables in a database.

When constructing a query, using SELECT allows you to define exactly what data you want to see in the result set. For example, a basic SQL query such as "SELECT first_name, last_name FROM employees" instructs the database to return the first and last names of employees records.

The other options do not serve this function within SQL syntax. LIST, GET, and FIND are not recognized SQL commands for querying data. Instead, SELECT is universally accepted across SQL databases to initiate a data retrieval operation. This makes SELECT an essential building block for anyone working with SQL in the context of data analysis and querying databases.
