The correct answer is A. Plants release oxygen into the air.
Explanation
The atmosphere is the layer of gases that is concentrated around a planet or celestial body that is held in place thanks to gravity. On the other hand, the biosphere is the layer of the earth that is made up of all living organisms such as animals, plants, microbial, among others. According to the above, when a plant releases oxygen into the air, the biosphere and the atmosphere are interacting because the plant is an organism that belongs to the biosphere and is releasing oxygen into the air, which is part of the atmosphere. So the correct answer is A. Plants release oxygen into the air
