B is correct
Health identifies the current problems in the system or issues that need to be resolved immediately to avoid problems. Therefore, health is the first high-level indicator that you should look at to see if your system needs immediate attention. The Health badge breaks down into several sub-badges: Workload, Anomalies, and Faults.

The Health badge summarizes workload, anomalies, and faults.
The Workload badge shows how hard an object is working. A higher workload score indicates that an object is doing more work. Obviously, you don’t want objects out there doing zero work, as that is waste but, as the same time, you also don’t want objects completely maxed out with a workload score of 100 either. Workload is an absolute measurement that calculates the demand for a resource divided by the capacity of an object. Resources might include CPU, memory, disk I/O, or network I/O. vC Ops will help you to balance workload across your resource objects effectively.
The Anomalies badge indicates how the object is behaving currently compared to how it has behaved in the past. While small anomalies don’t always indicate something bad, large anomalies are likely an indicator of a problem. vC Ops uses anomalies to determine what is “normal” in the your vSphere infrastructure vs what is “abnormal”.
The Faults badge tells you if configuration issues have occurred for an object. Faults are given priority over anomalies and workload when calculating health. Faults are calculated based on the events received from VMware vCenter about an object. Examples of events that might generate faults are ESXi host memory errors, loss of network or HBA redundancy, a failover event in a HA cluster, or hardware events (like high CPU temperature) received from CIM events.

To summarize:
The health badge is a weighted combination of (minor badges) Workload, Anomalies and Faults badges.
