Answer & Explanation
The correct answer is Option B: Over pressurization of the CO2 discharge piping.
A safety relief device, often a bursting disc, is installed on CO2 discharge piping to prevent over-pressurization. In the event of an abnormal pressure build-up, it ruptures to release the CO2, protecting the piping system from damage or catastrophic failure, compliant with the FSS Code.
