In which situation is running an antivirus scan most appropriate?

Answer and explanation

Correct answer: When the computer behaves unusually after opening an unknown file

The governing concept is basic computer security. An unknown file may contain malware, and unusual behavior such as repeated pop-ups, unexpected slowdowns, or unfamiliar messages can indicate infection. Running an antivirus scan is therefore most appropriate in situation B; the scan can detect or quarantine threats. A clean screen, paper in a printer, or a new mouse does not by itself provide a reason to scan for malware.
