Correct option is B
Carbon monoxide (CO) is a colorless, odorless, tasteless, and highly poisonous gas. It's also known as the "silent killer" because it's undetectable by human senses.
· Carbon monoxide is produced when fuels like wood, coal, oil, and natural gas are burned incompletely.
· It's found in furnaces, fireplaces, cars, and gas appliances like ovens, water heaters, and clothes dryers.
· Inhaling carbon monoxide can cause flu-like symptoms and can be fatal.
· Carbon monoxide binds with hemoglobin in the blood, preventing oxygen from reaching the body's organs.
