Correct Answer - Option 1 : heart
Carbon monoxide (CO is a colourless, odourless, tasteless, and toxic air pollutant which is produced in the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, oil, coal, and wood.
The emission of carbon monoxide CO from automobiles has caused a hazard to human health.
Breathing the high concentrations of CO typical of a polluted environment leads to reduced oxygen (O2) transport by haemoglobin and has health effects that include headaches, increased risk of chest pain for persons with heart disease, and impaired reaction timing.
The binding of carbon monoxide to hemoglobin, forming carboxyhemoglobin, reduces the amount of oxygen available to the heart muscle and other tissues for synthesizing ATP.
