An engineer received an alert affecting the degraded performance of a critical server. Analysis showed a heavy CPU and memory load. What is the next step the engineer should take to investigate this resource usage?

A. Run "ps -u" to find out who executed additional processes that caused a high load on a server B. Run "ps -ef" to understand which processes are taking a high amount of resources C. Run "ps -d" to decrease the priority state of high load processes to avoid resource exhaustion D. Run "ps -m" to capture the existing state of daemons and map required processes to find the gap
