A distance of the barite surface above the tank bottom

B total weight of barite in UPC (ullages per centimeter)

C percentage of barite in the tank

D distance of the barite surface below the tank cover

AI Explanation

The correct answer is D) distance of the barite surface below the tank cover. Ullage refers to the unfilled space in a tank, which is the distance between the surface of the contents (in this case, barite) and the top of the tank. This is the distance of the barite surface below the tank cover. The other options are incorrect because they do not accurately describe the definition of ullage. Option A refers to the distance above the tank bottom, option B is about the total weight of barite, and option C is the percentage of barite, none of which are the definition of ullage.
