The correct answer is B. Increase the amount of CPU resources available to the system. The uptime output shows a load average of 7.75, 5.72, 5.17 on a system with only 4 processors (nproc = 4). This indicates CPU saturation since the load averages are significantly higher than the number of available CPUs. Memory and swap usage are minimal, and vmstat shows no…

Explanation
The uptime output shows a load average of 7.75, 5.72, 5.17 on a system with only 4 processors (nproc = 4). This indicates CPU saturation since the load averages are significantly higher than the number of available CPUs. Memory and swap usage are minimal, and vmstat shows no I/O waits, so the bottleneck is CPU. Increasing CPU resources will help speed up the jobs.
