Which component can occur in the atmosphere as fine solid particles?
Answer and explanation
Correct answer: Dust
Atmospheric matter includes gases as well as suspended particulate matter. Dust consists of tiny solid mineral or soil particles that can remain temporarily suspended in air, so option A is correct. Nitrogen, oxygen, and argon are gases under ordinary atmospheric conditions; they are not fine solid particles in this context. The question therefore distinguishes particulate components such as dust from the major gaseous constituents.
