One of the limitations of foam as an extinguishing agent is that foam _______________.

A conducts electricity
B cannot be made with salt water
C is corrosive and a hazard to fire fighters
D is heavier than oil and sinks below its surface
AI Explanation

The correct answer is A) conducts electricity. Foam is a common extinguishing agent used in the maritime industry, but one of its key limitations is that it conducts electricity. This means that if the fire involves energized electrical equipment, the foam can transmit the electrical current, posing a significant hazard to firefighters. The other answer choices are incorrect - foam can be made with salt water, it is not corrosive or a hazard to firefighters, and it is actually lighter than oil, allowing it to float on the surface and smother the fire.
