Answer: JOIN
The SELECT clause (A) is used to specify the columns to be retrieved from the database, but it does not perform joins between tables. The FROM clause (B) specifies the primary table from which to retrieve data, but it does not perform joins. The WHERE clause (D) is used to filter the data based on specific conditions, but it does not perform joins. The JOIN clause (C) is specifically designed for joining data from two or more tables based on a common column, making it the most useful clause for this task.
