Question

Air is a/an:

• A. Compound
• B. Element
• C. Electrolyte
• D. None of the above

Hint:

Air is a mixture of gases, not a single element, compound, or electrolyte. The classification of matter depends on whether it is a pure substance or a mixture.

Answer 1

The Correct Option is D

Air is a mixture of various gases, including nitrogen, oxygen, carbon dioxide, argon, and other trace gases. It is not a single compound or element, and therefore cannot be classified as either. An electrolyte is a substance that conducts electricity when dissolved in water, which is not the case with air. Thus, the correct answer is \( \boxed{\text{None of the above}} \).
