Answer 1

The criteria > all () in a query is used to check if a value is greater than or equal to any of the values returned by a subquery. Therefore the correct answer is d) it returns true if a value is greater than or equal to any of the values returned by the subquery.

Step-by-step explanation:

The criteria > all () in a query is used to determine if a value is greater than all the values returned by a subquery.

In this case, the correct answer is option d) it returns true if a value is greater than or equal to any of the values returned by the subquery.

For example, if the subquery returns values [10, 20, 30], using the criteria > all () will return true for a value greater than or equal to 10, 20, or 30.
