What security risk can arise when file extensions are hidden?

Answer and explanation

Correct answer: A harmful file may appear like a normal document

Visible extensions help a user identify the actual type of a file before opening it. When extensions are hidden, a malicious executable can use a familiar-looking name, such as invoice.pdf, while its complete name may actually end in an executable extension. This can mislead the user into opening malware. Therefore, option D is correct; hiding extensions does not change file size or affect monitor and printer performance.
