Option A is incorrect because Microsoft Viva Insights provides personalized recommendations to help your users gain better insights and build better work habits; this tool will not suffice the requirements.
Option B is Incorrect because Microsoft Defender for Cloud Is a security solution for cloud security posture and will not provide the necessary features to identify personal data.
Option C is correct because Privacy Risk Management in Microsoft Priva gives organizations the ability to configure policies that detect privacy risks in your Microsoft 365 environment.
Option D is incorrect because Microsoft Purview eDiscovery is a tool used to discover and identify electronic information that can be used as evidence in legal cases; this will not meet the required objective.

Hybrid Connections can connect Azure App Service Web Apps to on-premises resources that use a static TCP port. Supported resources include Microsoft SQL Server, MySQL, HTTP Web APIs, Mobile Services, and most custom Web Services.

Note: You can use an Azure App Service Hybrid Connections. To do this, you need to add and create Hybrid Connections in your app. You will download and install an agent (the Hybrid Connection Manager) in the database server or another server which is in the same network as the on-premise database.
You configure a logical connection on your app service or web app.
A small agent, the Hybrid Connection Manager, is downloaded and installed on a Windows Server (2012 or later) running in the remote network (on-premises or anywhere) that you need to communicate with.
You log into your Azure subscription in the Hybrid Connection manager and select the logical connection in your app service.
The Hybrid Connection Manager will initiate a secure tunnel out (TCP 80/443) to your app service in Azure.
Your app service can now communicate with TCP-based services, on Windows or Linux, in the remote network via the Hybrid Connection Manager.
You could get more details on how to Connect Azure Web Apps To On-Premises.

You should read Microburst toolkit - it is an open-source tool. Find Get-AZStorageKeysREST.ps1 it tries to enumerate all storage accounts then the respective storage keys. There is nothing to do with anonymous access here. Even if a storage account allows public access you can't get the key without being authenticated and authorized.
The preventive control here is to manage Shared Key Authorization.

Secure management ports - Brute force attacks often target management ports. Use these recommendations to reduce your exposure with tools like just-in-time VM access and network security groups.
Recommendations:
- Internet-facing virtual machines should be protected with network security groups
- Management ports of virtual machines should be protected with just-in-time network access control
- Management ports should be closed on your virtual machines
