Solution
The unique aspect about a correlated subquery is that it depends on input from the outer query to return values. Unlike a regular subquery, which can be executed independently, a correlated subquery cannot be executed as a standalone query because it is linked to the outer query. Furthermore, it does not always appear in the WHERE clause; it can appear in any clause such as SELECT, FROM, WHERE, or HAVING depending on the specific SQL statement.
