CThe cylinders are mounted horizontally.
DIt has distribution piping installed permanently.
AI Explanation
The correct answer is B) It has a portable hose and nozzle. A semi-portable CO2 system is designed to be easily moved and relocated as needed, so it must have a portable hose and nozzle that can be connected to the CO2 cylinders. This allows the system to be used in different areas of a vessel as required. The other options are not characteristic of a semi-portable system - the cylinders are not required to weigh less than 50 pounds, they are typically mounted vertically, and the distribution piping is not permanently installed.
