Which function is NOT provided by the scrubber of an inert gas system?

Correct Answer: Option C — Maintains gas pressure in the tanks.

The scrubber's primary function is to cool the hot flue gases and remove particulate matter (soot) and sulfur oxides (SOx) before the gas enters the cargo tanks. It does not control the pressure of the inert gas; that function is managed by the inert gas blowers and pressure control valves.
