Question 31General Subjects - QMED

The correct answer is D) Innage is the distance between the surface of the liquid and the bottom of the tank, and ullage is the distance between the surface of the liquid and the top of the tank. This is the correct answer because it accurately describes the definitions of innage and ullage tank soundings. Innage refers to the depth of the liquid in the tank, measured from the surface of the liquid to the bottom of the tank. Ullage refers to the empty space in the tank, measured from the surface of the liquid to the top of the tank. The other options are incorrect because they do not properly define the terms innage and ullage in relation to the position of the liquid surface within the tank.
