Air
A
Heterogeneous
B
Homogeneous
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Despite the fact that air is a mixture of several gases, it is a homogeneous mixture since it seems uniform everywhere and its constituents are difficult to detect. Furthermore, simple mechanical methods are unable to separate distinct components of air. Hence, it is classified as a homogenous mixture.

Detailed explanation-2: -The air that we breathe is a homogeneous mixture of oxygen, nitrogen, argon, and carbon dioxide, along with other elements in smaller amounts. Air, neon, nitrous oxide, natural gas are all examples of homogeneous mixture.

Detailed explanation-3: -One of the properties of gases is that they mix with each other. When they do so, they become a solution-a homogeneous mixture. Some of the properties of gas mixtures are easy to determine if we know the composition of the gases in the mix. In gas mixtures, each component in the gas phase can be treated separately.
