A student opens a file based only on its name, and a harmful program becomes active. Which precaution was missed?

Answer and explanation

Correct answer: Checking the file source and actual type

The governing concept is safe file handling. A filename can be misleading, and a harmful executable may be disguised with an attractive document-like name. Before opening an unfamiliar file, the user should consider its source, inspect the complete extension when possible, scan it with trusted security software, and avoid unexpected attachments. Option D is correct; monitor brightness, folder colour, and printer checks do not establish file safety.
