Conditional Access session controls enable user app access and sessions to be monitored and controlled in real time based on access and session policies.

Based on this definition, the best answer for your question is B. enable limited experiences, such as blocking download of sensitive information.

Security defaults make it easy to protect your organization with the following preconfigured security settings:

Requiring all users to register for Azure AD Multi-Factor Authentication.

Requiring administrators to do multi-factor authentication.

Blocking legacy authentication protocols.

Requiring users to do multi-factor authentication when necessary.

Protecting privileged activities like access to the Azure portal.

In Microsoft 365, Data Loss Prevention (DLP) policies are designed to “help you identify, monitor, and automatically protect sensitive information” across services such as Exchange Online, SharePoint Online, OneDrive, and Microsoft Teams. Microsoft’s guidance explains that DLP uses sensitive information types—including built-in classifiers like Credit Card Number—to detect when content matches a defined pattern and then enforce protective actions. With DLP, you can create rules that trigger when email messages contain customer lists with credit card numbers, and choose actions to block the message, restrict access, or notify and educate users via policy tips and incident reports. Microsoft further notes that DLP “prevents the accidental sharing of sensitive information,” can require user justification to override, and supports granular conditions (e.g., number of matches, recipients internal vs. external) to ensure that only risky transmissions are stopped. By applying a DLP policy to Exchange with the Credit Card Number sensitive info type, an organization can block or quarantine outbound mail that includes those numbers, thereby reducing regulatory and data-exposure risk. Other options listed—retention policies, conditional access, and information barriers—serve different purposes (data lifecycle, access/authentication conditions, and restricting communication between groups) and do not inspect message contents for sensitive data. Hence, DLP policies are the correct control to restrict sending emails that contain customer lists and associated credit card numbers.

Microsoft documents for Defender for Endpoint (MDE) describe it as an enterprise endpoint security platform that supports Windows 10/11, Windows Server, Linux, macOS, and mobile platforms (Android and iOS/iPadOS). The platform provides threat and vulnerability management, attack surface reduction, next-generation protection, endpoint detection and response, and automated investigation and remediation across those supported operating systems. Because MDE supports Windows client operating systems and servers, it can also be used on Azure virtual machines that run supported Windows versions; onboarding methods include local scripts, Microsoft Endpoint Manager, or cloud integrations, allowing VM endpoints to receive the same protection and EDR capabilities as physical devices.

By contrast, malware scanning in SharePoint Online, OneDrive, and Microsoft Teams is provided by Microsoft Defender for Office 365 (Safe Attachments for SharePoint, OneDrive, and Teams)—a different service within the Microsoft 365 Defender family. This service analyzes files as they are uploaded or shared to detect and block malicious content in collaboration workloads, which is outside the scope of MDE’s endpoint-focused protections. Therefore: Android protection (Yes), Azure VMs running Windows 10 (Yes), and SharePoint Online anti-virus protection by MDE (No, handled by Defender for Office 365).
