The correct answer is B. Argon.
Explanation:
The Earth's atmosphere is made up of various gases, and noble gases make up a small percentage of it. Among the noble gases, Argon (Ar) is the most abundant.
Argon makes up about 0.93% of the Earth's atmosphere by volume.
Neon (Ne) is much less abundant, making up about 0.0018% of the atmosphere.
Krypton (Kr) and Xenon (Xe) are even less abundant than neon, occurring in trace amounts.
The high abundance of argon in the atmosphere is because it is chemically inert and does not easily react to form compounds, so it accumulates over time.
Thus, the most abundant noble gas in the atmosphere is B. Argon.
