C Correct answer
Explanation

On a clear, dark night with no light pollution, a human can see a candle flame from approximately 30 miles away. This remarkable range is due to the high contrast between the small, bright flame and the dark background. At 30 km or 30 feet, the candle would still be visible, but 30 miles represents the extreme limit of visibility under perfect conditions.
