Answer: WHERE
The SELECT clause (A) is used to specify the columns to be retrieved from the database, but it does not provide filtering capabilities. The FROM clause (B) specifies the table or tables from which to retrieve data, but it also does not filter the data. The GROUP BY clause (D) is used for aggregating data based on one or more columns, but it does not filter individual rows. The WHERE clause (C) is used to filter the data based on specific conditions, allowing you to select only the rows that meet the specified criteria. Therefore, the WHERE clause would be the most useful for filtering the data in this scenario.
