Answer & Explanation
The correct answer is Option D: 140 Deg F (60 Deg C) and above.
Non-volatile petroleum liquids are defined by their higher flash points. According to international safety standards for tanker operations, a liquid with a closed-cup flash point of 60°C (140°F) or above is considered non-volatile, reducing the risk of vapor accumulation at ambient temperatures.
