--- End quote ---
the questions asks which of them wouldn't work. Since iron,copper and aluminium are conductors the setup will work but if nylon fishing net it used it won't be able to conduct and the experiment won't work. I hope it's clear

heating simply does not demagnetize the magnet it needs to be red hot and then blown with a hammer. So it is A.

but its an iron rod which already demagnetised...
