52 should be b&c. controller failure has nothing to do with this type of issue. degraded state tells us its a raid issue, and if the os is missing then the bootable device isnt found. the only other consideration could be data loss but thats somewhat broad whereas b&c show understanding of the specific issues the question is asking about.

question 16 should be b (changing the connector settings on the monitor) pc and monitor were powered on. the lights on the pc are on indicating power. the monitor is showing an error text indicating that it is receiving power too. this is a clear sign of having the wrong input selected on the monitor. thus, the "connector setting" needs to be switched from hdmi to display port on the monitor so it receives the signal from the pc, or the other way around (display port to hdmi).
