Answer 1

The correct option is (d) $ary

To explain: The Perl Non-handle variable ‘$ary’ is an array or list representing a row of values returned by a query. ‘$rc’ returns code from operations that return true or false. ‘$rv’ returns value from operations that return an integer. ‘$rows’ returns value from operations that return a row count.
