This question was addressed to me by my college director while I was bunking the class.

Answer 1

Correct answer is (d) $ary

For explanation I would say: 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.
