Question

Quizplus · Accepted Answer

Volatile organic compounds (VOCs) are not exclusively gases in the atmosphere, but they share the characteristic of being able to vaporize and enter the atmosphere under normal conditions. Choices B, C, D, and E are incorrect because VOCs can also come from natural sources, may have odors, and are not exclusively from fossil fuels or colorless and odorless.
