What is the generic handle whose meaning depends on context?(a) $dbh(b) $sth(c) $fh(d) $h

Answer» Right option is (d) $h

To explain I would say: The variable named ‘$fh’ is a handle to an open file. ‘$h’ is a generic handle and the meaning depends on context. ‘$dbh’ is a handle to a database object. ‘$sth’ is a handle to a query object.
