Answer:
<u><em>The correct option is C) Prions</em></u>
Explanation:
Bovine spongiform encephalopathy (BSE) or Mad Cow Disease is a disease which occurs due to transmissible particles known as prions. Prions cannot be considered as living organisms as they do not acquire many of the living characteristics. They are just considered as a protein which gest converted into an activated, toxic form as soon as they encounter a host cell. This toxic protein harms the central nervous system (CNS) of the cow host and is transmissible.

CO₂ is the waste product of respiration of cells. Oxygen, on the other hand, is required in cellular respiration. Therefore at the alveolar in the lungs of an organism, CO₂ will be expelled while O₂ will be taken in.
Explanation:
This occurs passively due to the diffusion gradient, CO₂ usually has a higher concentration in the blood and lower concentration in alveoli hence this gas diffuses from the bloodstream into the lungs. On the other hand, oxygen is higher in concentration in the alveoli than in the blood capillaries hence difuses into the blood and taken to the cell for respiration. The CO₂ in the lungs is then expelled through exhalation of the lungs.
