The answer is A. nitrogen.
Here's why:
* Natural Water: Rivers and ponds have water that's been exposed to the air.
* Air Composition: Air is mostly made up of nitrogen (about 78%), oxygen (about 21%), and a tiny bit of carbon dioxide.
* Dissolved Gases: When water is in contact with air, some of these gases dissolve in it.
So, natural water will contain dissolved oxygen, carbon dioxide, and nitrogen.
