The correct answer is D) all of the above. Air leaking into a flash type distilling plant can occur through valve stems, gage glass packing, and gasketed joints. These are all potential points of air leakage in a distilling plant system. Proper maintenance and inspection of these components is critical to ensure the integrity of the system and prevent air leaks, which can impact the efficiency and safety of the distilling plant operation. The other answer choices are also correct, as each represents a potential source of air leakage in this type of system.
