How can the atmospheric significance of argon be best understood?
Answer and explanation
Correct answer: It is a stable and inert component in small amount
Argon is a noble gas and is chemically inert under ordinary atmospheric conditions. It occurs as a small but relatively stable proportion of dry air, so it is classified as a permanent atmospheric component rather than a variable component such as water vapour. Option A is correct. Rainfall involves water, oxygen is central to aerobic respiration, and ozone is made of O₃, not argon.
