Correct Answer

A

Explanation

Natural water collected from rivers and ponds primarily contains dissolved gases such as oxygen (O2), carbon dioxide (CO2), and nitrogen (N2). These gases can be present in varying concentrations depending on factors such as temperature, atmospheric pressure, and the surrounding environment.

The presence of other gases like hydrogen (H2), chlorine (Cl2), and sulfur dioxide (SO2) is generally not common in significant amounts in natural freshwater. These gases may be present in trace amounts, but they are not typically major components of the dissolved gases in natural water bodies.

It's worth noting that the composition of natural water can vary based on geographical location, human activities, and environmental conditions. Additionally, water may contain dissolved ions, minerals, and organic matter along with gases, contributing to its overall chemical composition.
