To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) JOIN - The JOIN clause is used to combine records from two or more tables based on a related column between them. While it is commonly used in SQL queries, it is not required to get information from a database.

Option B) ON - The ON clause is used in conjunction with the JOIN clause to specify the join condition between tables. It is not required on its own to retrieve information from a database.

Option C) ORDER BY - The ORDER BY clause is used to sort the result set of a query based on one or more columns. While it is commonly used to organize the output, it is not required to fetch information from a database.

Option D) SELECT - The SELECT clause is used to retrieve data from a database. It is essential in an SQL query as it specifies which columns or expressions to include in the result set.

Option E) WHERE - The WHERE clause is used to filter records based on a specified condition. It is commonly used to retrieve specific data from a table. While it is not always required, it is often used in SQL queries to narrow down the result set.

The correct answer is D) SELECT. This option is correct because the SELECT clause is necessary in an SQL query to specify the columns or expressions to retrieve from a database.
