Aldrin directly attacks the nervous system, causing tremors and convulsions.

DDT is a persistent organochlorine known mainly for bioaccumulating in fatty tissue.

Organic phosphates harm nerves too, but aldrin is the classic organochlorine linked to nervous damage here.

Dismissing all choices is wrong because aldrin clearly affects the nervous system.

Aldrin readily converts to dieldrin, which is even more neurotoxic.

It is a persistent organic pollutant restricted under global treaties.
