Correct Statement: 1

Yes, carbon monoxide (CO) can lower the amount of oxygen in your blood. When inhaled, CO binds to hemoglobin in red blood cells, forming carboxyhemoglobin (COHb). This reduces the amount of hemoglobin available to carry oxygen.

Consider the following statements about the carbon monoxide:1. It lowe...
**Statement 1: Carbon monoxide lowers the amount of oxygen that enters our blood.**
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is highly toxic to humans and animals. When inhaled, it binds to hemoglobin in red blood cells, forming carboxyhemoglobin. This reduces the oxygen-carrying capacity of the blood, leading to a condition called carbon monoxide poisoning.

When carbon monoxide enters the bloodstream, it has a much higher affinity for hemoglobin than oxygen. This means that even at low concentrations of carbon monoxide, it can displace oxygen from hemoglobin. As a result, less oxygen is available to be transported to the body's tissues and organs, leading to oxygen deprivation.

The symptoms of carbon monoxide poisoning can vary depending on the level and duration of exposure. Mild symptoms may include headache, dizziness, nausea, and fatigue, while severe exposure can cause confusion, loss of consciousness, and even death.

**Statement 2: Carbon monoxide is produced from the combustion of natural and synthetic products which gives it a light black color.**
This statement is incorrect. Carbon monoxide is a colorless gas and does not have a light black color. The color of the flame during combustion may vary depending on the fuel being burned, but carbon monoxide itself is not visible.

Carbon monoxide is produced when fuels such as coal, oil, natural gas, wood, and gasoline undergo incomplete combustion. Incomplete combustion occurs when there is not enough oxygen present for the fuel to burn completely, leading to the production of carbon monoxide and other harmful byproducts.

Carbon monoxide is often produced by vehicles, power plants, furnaces, and other sources of combustion. It is important to ensure proper ventilation and use of carbon monoxide detectors to prevent exposure to this toxic gas.

**Conclusion:**
Based on the explanations above, it is clear that statement 1 is correct, as carbon monoxide does lower the amount of oxygen that enters our blood. However, statement 2 is incorrect, as carbon monoxide is a colorless gas and does not have a light black color. Therefore, the correct answer is option 'A' - 1 only.
