b. Cyanide prevents oxygen frombeing used in the brain.

Answer 1

The answer is A.

Step-by-step explanation:

In the case of cyanide poisining which prevents the oxygen from being used by the body, the brain is one of the first organs that gets effected because it uses around 20% of the total oxygen intake of the body and the other systems and organs mostly depend on the brain to function properly so the brain runs out of oxygen before the other parts of the body.
