Bradley Banks · Answer 1

option D. continuous muscle spasms and convulsions

Explanation:

Sarin is an organophosphorus synthetic compound and is highly toxic. Sarin toxic is colorless and odorless. It act as a potent nerve agent and used as a chemical weapon. This toxic substance binds irreversibly with the enzyme acetylcholinesterase. This enzyme is responsible for degrading acetylcholine. The toxin interferes with the normal functioning mechanism of nervous system.

The organism poisoned by sarin could suffer paralysis, vomiting, continuous muscle spasms and convulsions. Thus, option D is correct.
