AI Explanation

The correct answer is A) natural or mechanical ventilation. The accumulation of dangerous fumes generated by the storage batteries is best prevented by providing adequate ventilation, either natural or mechanical. This is in accordance with Coast Guard regulations, which require battery compartments to be properly ventilated to prevent the buildup of explosive hydrogen gas. Options B, C, and D do not directly address the issue of ventilation, which is the primary means of preventing dangerous fume accumulation.
