Correct Answer : Option b

Explanation
Snake Venom: It is a potent mixture of toxic proteins that causes severe damage to the human body.

Statement 1 is not correct: Haemotoxins primarily affect the blood and blood vessels, leading to hemorrhaging, blood clotting issues, and damage to blood vessels, rather than directly dissolving tissue. While they can cause local tissue damage due to blood leakage and clotting problems, they don't "dissolve" tissue in the way the statement suggests.

Statement 2 is correct: Neurotoxins found in snake venom target the nervous system. They can block the transmission of nerve signals by affecting synapses, receptors, or ion channels, leading to paralysis. A well-known example is the venom of cobra and krait snakes, which can cause paralysis by affecting neuromuscular junctions.

Statement 3 is not correct: Cytotoxins are toxins that damage cells, particularly by causing cell death at the site of the bite. They can cause local tissue necrosis but are not primarily involved in disrupting blood clotting. Disruption of clotting is more characteristic of hemotoxins, not cytotoxins.
