AI Explanation

The correct answer is A) flame screen. A flame screen is a device fitted over the discharge opening on a relief valve. It consists of one or two woven wire fabrics that serve to prevent the passage of flame through the valve, in case of a fire or explosion. This is a safety feature required by regulations to prevent the ignition of surrounding flammable materials. The other answer choices are incorrect because: B) a restrictor is a different type of valve component, C) a filter is used for a different purpose, and D) a stopper is not the correct term for this type of device.
