The correct answer is A. Data access governance in the SharePoint admin center . Microsoft Learn documents Data access governance reports in the SharePoint admin center as the reporting solution used to understand data exposure, including permission structure and sharing link activity . Microsoft specifically states that the site permissions snapshot report provides visibility across SharePoint and OneDrive sites , helping administrators understand current permissions exposure, and that separate reports are created for SharePoint and OneDrive . Microsoft also documents sharing links activity reports as part of Data access governance for monitoring link-sharing activity, and notes that OneDrive support is available through PowerShell for those reports. Together, this is the Microsoft reporting capability aligned with permissions and active sharing links for OneDrive content.

The other options do not fit this requirement. Microsoft 365 admin center reports focus mainly on usage and activity reporting, not detailed permissions and sharing-link governance. Defender Audit is for security investigation activity, and Purview eDiscovery is for legal and investigative content search, not for generating OneDrive permissions and sharing-link governance reports. Therefore, the best Microsoft-documented answer is Data access governance in the SharePoint admin center .
