C Correct answer
Explanation

Air is present everywhere on Earth - in the atmosphere, in water, in soil, and even inside living organisms. Sunlight is not available everywhere (underground, deep ocean, night). Atmosphere is the layer of gases surrounding Earth but isn't present everywhere (outer space). Water is limited to specific locations. Air is the most ubiquitous abiotic component.
