In the email filtering lab, which option blocks content from unknown senders by blocking attachments, pictures, and links?

• A. Block emails from unknown senders
• B. Remove attachments from unknown senders
• C. Block attachments, pictures, and links for anyone not in my safe senders list
• D. Warn before opening links from unknown senders

Answer: (C)

The key idea is controlling content from senders you don’t trust by applying a policy to what such messages can include. The option that blocks attachments, pictures, and links for anyone not in your safe senders list enforces that policy across all content types. By not loading or displaying external content from untrusted senders, it directly reduces the risk of phishing, malware, and drive-by exploits. It’s more comprehensive than simply blocking emails from unknown senders (which would block everything from those senders) or just removing attachments (which leaves links and images that can still be dangerous). A warning before opening links is helpful, but it relies on user judgment rather than preventing harm.
