D. the first column in the first SELECT of the compound query.
When using SET operators such as INTERSECT in a SQL statement, the default column or columns for sorting output is based on the column order in the first SELECT statement of the compound query. Specifically, the first column in the first SELECT statement is used to sort the results. If you want to change the sort order or use a different column for sorting, you can use an ORDER BY clause at the end of the compound query.
