• A. Green coloured lungs
• B. Lungs with green alga
• C. Lungs of Green coloured animals
• D. Forests

Answer 1

The correct option is D Forests

Green plants absorb carbon dioxide during the process of photosynthesis and release oxygen into the atmosphere. In the same way, our lungs absorb carbon dioxide from the blood and infuse it with oxygen. Forests, therefore, act as earth’s air purifiers by absorbing the large amounts of carbon dioxide from the atmosphere. Thus the correct answer is option D.
