C is the right answer here, no question about it. Any time you get an unsolicited email with an attachment claiming to be a critical OS patch, that is a massive red flag because legitimate IT departments do not distribute security updates through personal email with zip files. Option D is flat out wrong, email servers do catch a lot of malware but they are not perfect and plenty of malicious files slip through every day. You call IT first, confirm the file is legit, and let them walk you through the proper update channel, which is almost never "open this zip a coworker emailed you."

Got C on my first try, my mentor drilled "verify before you click" into me.

That is solid advice but I would add "verify AND re-read the stem" because a lot of traps are baked into how the question is worded, not just the answer choices.

Thought D was safe since our mail filter is solid, but legit patches never come via email attachment, call IT first.
