You implement Microsoft Defender for Office 365 safe attachments policies for all users.
User reports that email messages containing attachments take longer than expected to be received.
You need to reduce the amount of time it takes to receive email messages that contain attachments. The solution must ensure that all attachments are scanned for malware. Attachments that have malware must be blocked.
What should you do?

Answer options

• A. Set the action to Block
• B. Add an exception
• C. Add a condition
• D. Set the action to Dynamic Delivery
