Atmospheric Science

Step 1: Understanding the Concept:
The question asks to arrange the given gases in order of their abundance in the Earth's dry atmosphere, from the least abundant to the most abundant.

Step 3: Detailed Explanation:
The approximate concentrations of these gases in dry air are:

Neon (E) \textless Carbon dioxide (B) \textless Argon (D) \textless Oxygen (A) \textless Nitrogen (C).

Step 4: Final Answer:
The correct order of gases in increasing concentration is: (E) Neon (~18 ppm), (B) Carbon dioxide (~400 ppm), (D) Argon (~9300 ppm or 0.93%), (A) Oxygen (~20.95%), and (C) Nitrogen (~78.08%). This corresponds to the sequence (E), (B), (D), (A), (C).
