B) False

Answer 1

The statement is false; SQL queries do not automatically eliminate duplicates. The DISTINCT keyword must be used in a SELECT statement to remove duplicate entries.

Step-by-step explanation:

The statement "A SQL query automatically eliminates duplicates" is false. In SQL, the SELECT statement is used to retrieve data from a database. By default, SELECT queries do not eliminate duplicates. If you want to remove duplicates from the result set, you must use the DISTINCT keyword in your SELECT statement. For example, SELECT DISTINCT column_name FROM table_name; will return unique values by eliminating duplicates in the specified column.
