Answer: Option B) is toxic to red blood cells.
Explanation:
Partial hydrolysis of lecithin by lecithinases (enzyme in black widow spiders and snakes venom) causes the removal of only one fatty acid to yield lysolecithins, which when subjected to the bloodstream by sting as a result of spider bite causes the rupture of red blood cells.
Thus, the mechanism is that it is toxic to red blood cells.
