What statement best represents the characteristics of an innage tape and bob for the purposes of taking a vented tank sounding?

Correct Answer: Option B — The bob has a pointed end and sinks in the liquid when lowered by the tape.

An innage tape uses a weighted bob with a pointed end designed to sink through the liquid to the bottom of the tank. The depth of the liquid is read directly from the tape at the surface level, providing a precise measurement of the total liquid volume present.
