Solution
The correct option is C Malathion A number of insecticides, the phenothiazines, organophosphates such as dichlorvos, malathion and parathion, are nerve agents.
Nerve agents are a class of phosphorus-containing organic chemicals (organophosphates), that disrupt the mechanism by which nerves transfer messages to organs. The disruption is caused by blocking acetylcholinesterase, an enzyme that normally destroys acetylcholine, a neurotransmitter.
As chemical weapons, they are classified as weapons of mass destruction by the United Nations.
