Answer: B

Explanation:

Reference: https://www.cisco.com/c/en/us/products/collateral/servers-unified-computing/ucs-b-series-blade-servers/white-paper-c11-744678.html. For Package C State limit default: C0/C1 State; Max Per: Platform Default; Low-latenc: Platform Default; Energy Effi: C6 Retention

https://www.cisco.com/c/dam/en/us/products/collateral/servers-unified-computing/ucs-b-series-blade-servers/whitepaper_c11-740098.pdf he higher the package C-state, the lower the power use of that idle package state. The default setting, Package C6 (nonretention), is the lowest power idle package state supported by the processor.

"Whether the BIOS sends the C6 report to the operating system. When the OS receives the report, it can transition the processor into the lower C6 power state to decrease energy usage while maintaining optimal processor performance"
