Detailed Solution

Oxygen is released by plants but not animals. Hence, (R) is not the correct explanation of (A).

The Amazon rainforest is often referred to as the “lungs of the planet” because it produces approximately 20% of the world's oxygen. This is due to the vast amount of trees in the rainforest that absorb carbon dioxide and release oxygen through the process of photosynthesis.
It may be noted that the Amazonian rainforest in South America is home to more than 40,000 species of plants, 3,000 species of fish, 1,300 species of birds, 427 species of mammals, 427 species of amphibians, 378 species of reptiles, and more than 1,25,000 species of invertebrates.
