B it allows the inert gas piping to be used for gas freeing the tanks
C it prevents the flue gas from falling below an oxygen content of 3%
D it enables outside air to mix with and to cool the hot flue gases
AI Explanation

The correct answer is B) it allows the inert gas piping to be used for gas freeing the tanks. The fresh air intake of the inert gas system is designed to allow the inert gas piping to be used for gas freeing the tanks. This enables the system to effectively remove flammable vapors from the cargo tanks by flushing them with fresh air through the inert gas piping. The other answer choices are incorrect: A) is incorrect because the fresh air intake is not related to the deck water seal. C) is incorrect because the fresh air intake does not prevent the flue gas from falling below a specific oxygen content. D) is incorrect because the fresh air intake is not meant to mix with and cool the hot flue gases.
