The combination of multiple conditions in a JOIN operation is often facilitated by the ________ clause.
- WHERE

- ON

In SQL, the combination of multiple conditions in a JOIN operation is facilitated by the 'ON' clause. It specifies the conditions that must be met for rows to be combined across tables. This is different from the 'WHERE' clause, which filters rows before the JOIN, and 'GROUP BY' and 'HAVING,' which are used for aggregation.
