A free password security and password recovery tool that supports many operating systems.

• A. Cain and Abel
• B. Password Safe
• C. KeePass Password Safe
• D. John the Ripper

Answer: (D)

The concept here is identifying a tool used for testing password security and recovering passwords that runs on multiple operating systems and is available free. John the Ripper fits this description best because it’s a free, open‑source password cracking utility designed to test and recover passwords across many platforms, including Linux, Windows, macOS, and BSD. It supports various attack methods (like dictionary and brute-force) and a wide range of hash formats, making it versatile for security assessments and password recovery tasks. Cain and Abel is primarily Windows-focused and not as cross‑platform, while Password Safe and KeePass are password managers meant to store credentials—not crack or recover forgotten ones. So the tool that best matches a free, cross‑platform password security and recovery solution is John the Ripper.
