AI Explanation
The correct answer is B) Plastic refractory. Plastic refractory is a suitable material for making temporary emergency repairs to brickwork in a boiler furnace. It is a specialized refractory compound that can withstand high temperatures and is designed for quick, temporary fixes to furnace linings or other refractory structures. The other options, such as calcined diatomaceous earth, insulating block, or air setting mortar, would not provide the necessary heat resistance and structural integrity required for this type of emergency repair in a boiler furnace.
