AI Explanation
The correct answer is B) The bob has a pointed end and sinks in the liquid when lowered by the tape.
For taking a vented tank sounding, an innage tape and bob is used. The bob has a pointed end to allow it to pierce the surface of the liquid and sink to the bottom of the tank. This allows the full depth of the liquid to be measured accurately. Options A, C, and D describe characteristics that would not allow the bob to properly sink and measure the full depth.
