Your organization has a policy against external media being used on the network without prior approval, and unknown executables are not allowed to be run on any corporate device. You examine this thumb drive and see that the files are named with unknown extensions. You want to analyze one of these files to see what it contains, so you download the file onto a standalone Windows machine with analysis software installed on it.

The file is a Windows executable. O B. Thefile is a Linux executable. C. Thefile is harmless and is a simple text file D. Thefile is a known piece of malware
