B. It decreases the flow of carbon dioxide in the blood.
• C. It prevents the free flow of oxygen in the blood.

Answer 1

C

Step-by-step explanation:

"What does carbon monoxide do to the human body?

Carbon monoxide is harmful when breathed because it displaces oxygen in the blood and deprives the heart, brain and other vital organs of oxygen. Large amounts of CO can overcome you in minutes without warning — causing you to lose consciousness and suffocate."

So this means it would prevent flow of oxygen and will be very lethal.
