All of the above

A toxic substance is a substance that can be poisonous or cause health effects.

Benzene is known to cause cancer, based on evidence from studies in both people and lab animals.Basically it is carcinogenic.

Toluene is irritating to the skin, eyes, and respiratory tract. It can cause systemic toxicity by ingestion or inhalation and is slowly absorbed through the skin.

Carbon tetrachloride is one of the most potent hepatotoxins (toxic to the liver), so much so that is widely used in scientific research to evaluate hepatoprotective agents.Exposure to high concentrations of carbon tetrachloride (including vapour) can affect the central nervous system, degenerate the liver and kidneys and prolonged exposure may lead to coma or death.
