A. Carbon dioxide
B. Carbon monoxide
C. Nitrogen
D. Hydrogen
Check Answer
The most toxic gas among the given options is Carbon monoxide. Therefore, option B is the correct answer.
Explanation:
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is highly toxic to humans and animals. It is produced by the incomplete combustion of fossil fuels such as coal, oil, and gas, as well as wood and other organic materials. Carbon monoxide is dangerous because it binds to hemoglobin in the blood, reducing its ability to carry oxygen to the body’s tissues. This can cause headaches, nausea, dizziness, confusion, and even death at high concentrations.
Option A (carbon dioxide) is a naturally occurring gas that is not toxic in normal concentrations, but can cause asphyxiation in high concentrations. Option C (nitrogen) is a naturally occurring gas that is not toxic in normal concentrations, but can cause asphyxiation in high concentrations. Option D (hydrogen) is a flammable gas that is not toxic in normal concentrations, but can be explosive in high concentrations.
