What is the default time range in Performance Hub?

When you first open Performance Hub for a managed database within Oracle Cloud Infrastructure (OCI) Database Management, the default time range selected is "Last 1 hour". This initial view provides administrators with an immediate snapshot of the most recent database activity and performance metrics. While other time ranges, such as 15 minutes, 24 hours, or a custom range, can be selected, the tool's default behavior is to display the past 60 minutes of data.

A. 15 Minutes is a selectable quick-pick option for a shorter, more granular view, but it is not the default time range.
C. 24 Hours is a common time frame for daily analysis and is a selectable option, but it is not the default view upon opening Performance Hub.
D. 1 Week provides a longer-term performance overview and is available for selection, but it is not the default setting.

Under the section "Use Performance Hub to Analyze Database Performance", the documentation states: "Time Range: Use the options at the top-right corner of the page to select a time range. By default, the Last 1 hour time range is selected and data for the last 60 minutes is displayed in Performance Hub."
