BIt is a colorless, odorless radioactive gas that can accumulate in tightly sealed buildings and cause lung cancerCorrect

CIt contaminates drinking water from surface runoff, though the exact requirements can vary somewhat by jurisdiction

DIt is produced by heating oil combustion

Why It is a colorless, odorless radioactive gas that can accumulate in tightly sealed buildings and cause lung cancer Is Correct

Answer B: It is a colorless, odorless radioactive gas that can accumulate in tightly sealed buildings and cause lung cancer

Radon is a naturally occurring radioactive gas that seeps from soil and rock. It can accumulate in tightly constructed buildings — a concern in Alaska where buildings are sealed for energy efficiency — and is the second leading cause of lung cancer.
