Which option best represents a group with variable and particulate nature among atmospheric components?
Answer and explanation
Correct answer: Water vapour and dust particles
The governing concept is the classification of atmospheric constituents by both variability and physical form. Water vapour is a variable gaseous component because its amount changes with temperature and weather. Dust particles are suspended solid materials whose concentration changes with wind, land use, and pollution. Thus option A contains both relevant types. Nitrogen and oxygen are relatively permanent gases, while the noble-gas pairs are not the best examples of variable particulate matter.
