Question 1212 Deck General

The correct answer is B) Maintains gas pressure in the tanks. The scrubber of an inert gas system is responsible for removing particulate matter and chemical impurities from the inert gas, as well as cooling the gas, but it does not maintain the gas pressure in the tanks. The gas pressure in the tanks is typically maintained by a separate pressure control system, not the scrubber. The other options are incorrect because the scrubber does in fact remove particulate matter (A) and chemical impurities (C), and it does cool the inert gas (D), but it does not maintain the gas pressure in the tanks.
