Answer: A
Explanation:
Reliability Monitor maintains up to a year of history for system stability and reliability events.
The System Stability Chart displays a rolling graph organized by date.
The top half of the System Stability Chart displays a graph of the Stability Index.
In the lower half of the chart, five rows track Reliability Events that either contribute to the stability measurement for the system or provide related information about software installation and removal.
When one or more Reliability Events of each type are detected, an icon appears in the column for that date.
For Software Installs and Uninstalls, an Information icon indicates a successful event of that type occurred, or a Warning icon indicates a failure of that type occurred.
For all other Reliability Event types, an Error icon indicates a failure of that type occurred.
