Why each option

Virus attacks are commonly caused by interacting with or executing files and applications obtained from untrusted or unreliable sources, regardless of the media type.

AInstalling an application from an unreliable sourceCorrect

Installing applications from untrusted sources, such as pirated software or unverified download sites, is a primary method for malware, including viruses, to infiltrate a system.

BDownloading a file from an unknown WebsiteCorrect

Downloading and opening files from unknown or suspicious websites can easily introduce viruses and other malicious software if the files are infected.

CInstalling a .DLL file from an unreliable sourceCorrect

Installing or placing dynamic-link library (.DLL) files from unreliable sources can introduce malicious code that executes within legitimate programs, leading to virus infections.

DUsing a floppy, a compact disk, or a pen drive from an unreliable sourceCorrect

Using removable media like floppy disks, compact disks, or USB pen drives from unreliable or unknown origins is a classic vector for spreading viruses if the media is infected.
