_____________ is the poisonous gas leaked during Bhopal gas tragedy

The correct answer is: Methyl Isocyanate (MIC).

Methyl isocyanate (MIC) is a highly toxic chemical used in the production of pesticides. It is a colorless, flammable liquid with a pungent odor. MIC is extremely toxic to humans and animals, and even a small amount can be fatal.

On December 2, 1984, a leak of MIC from a Union Carbide pesticide plant in Bhopal, India, killed an estimated 22,000 people and injured over 150,000 others. It is considered one of the worst industrial disasters in history.

The other options are incorrect.

• PVC (polyvinyl chloride) is a common plastic used in construction, packaging, and other applications. It is not a poisonous gas.
• Teflon is a fluoropolymer used in nonstick cookware and other applications. It is not a poisonous gas.
• Hydrogen sulfide is a flammable gas with a rotten egg smell. It is toxic in high concentrations.

I hope this helps!
