ABoth the vent pipe and the sounding tube attach to an end at an opening at the top of the tank.
BThe vent pipe attaches to and ends at an opening at the top of the tank, and the sounding tube passes through the tank top and extends almost to the tank bottom.
CBoth the vent pipe and the sounding tube pass through the tank top and extend almost to the tank bottom.
DThe sounding tube attaches to and ends at an opening at the top of the tank, and the vent pipe passes through the tank top and extends almost to the tank bottom.
AI Explanation

The correct answer is B. The vent pipe of a vented tank attaches to and ends at an opening at the top of the tank, allowing air to flow in and out as the tank level changes. The sounding tube, on the other hand, passes through the tank top and extends almost to the tank bottom, allowing the tank level to be measured. This configuration ensures that the tank can properly vent while also providing a means to determine the tank's contents. The other options are incorrect because they do not accurately describe the typical arrangement of the vent pipe and sounding tube on a vented tank. For example, option A suggests that both the vent pipe and sounding tube connect to the top of the tank, which is not the case, and options C and D describe incorrect placements of the vent pipe and sounding tube within the tank.
