AI Explanation
The correct answer is C) combustion air inlet. The illustration SG-0008 is depicting a typical marine boiler system. Arrow "B" points to the opening where combustion air enters the boiler to support the burning of fuel. This is the combustion air inlet, which is the correct answer. The other answer choices are incorrect because they do not accurately describe the component indicated by Arrow "B" in the illustration. A retractable soot blower, uptakes, and a regenerative air heater are different parts of a boiler system, but they are not what Arrow "B" is pointing to in this specific illustration.
