AI Explanation
The correct answer is C) flammable or toxic gases. A tank or compartment is considered "gas free" when there is an absence of dangerous concentrations of flammable or toxic gases. This is a standard requirement specified in maritime regulations and guidelines for ensuring the safety of personnel working in enclosed spaces on ships or other vessels. The other answer choices are incorrect because: A) the absence of any combustible liquid is not the sole criteria for being gas free, B) the absence of all flammable liquids does not necessarily mean the space is free of dangerous gases, and D) the absence of residues from cargo oil does not guarantee the absence of flammable or toxic gases.
