Explanation
Outer joins include LEFT OUTER JOIN, RIGHT OUTER JOIN, and FULL OUTER JOIN. Since both right and full outer joins exist, 'all of the above' is correct.
AI explanation
Beyond the left outer join, SQL also supports right outer joins and full outer joins (often just written as RIGHT JOIN and FULL JOIN), each of which is a legitimate "other" type of outer join alongside the left outer join. Since the listed options are just different ways of naming right and full outer joins, all of them qualify as valid answers to "another type of outer join," which is why "all of the above" is correct.
