Question

_________ have higher lung capacities than humans.

• A. Elephants
• B. Birds
• C. Cheetahs
• D. Both A and C

Answer 1

The correct option is D Both A and C

• The lungs are the primary organs of the respiratory system in humans and many other animals. Human lung size is determined by genetics, gender, and height.
• Different animals exhibit different lung capacities based on their activities. For example, cheetahs have evolved a much higher lung capacity than humans in order to provide oxygen to all the muscles in the body, allowing them to run very fast.
• Elephants also have a high lung capacity due to their large body and their need to take up oxygen in accordance with their body size. Hence, elephants and cheetahs have higher lung capacities than humans.
  

So, the correct answer is 'Both A and C'.
