Wow this brings back old memories from 1st year med school...and so my memory is a fragmented.

When I think of organophosphates, I think of chemical warfare agents such as sarin. But what comes to mind is that organophosphates are irreversible inhibitors of acetylcholinesterase at the neuromuscular junction (?). Hence, I would favor an answer that involves paralysis...and people would most likely die of respiratory paralysis.

My answer is E. But I could be barking up the wrong tree here.
