A password cracker is software that repeatedly makes guesses in order to crack the password.

• A. Firewall
• B. Password Manager
• C. Password Cracker
• D. Antivirus

Answer: (C)

The main idea here is recognizing a tool that is specifically designed to break into accounts by trying many password guesses. A password cracker operates by repeatedly guessing passwords—using brute-force or dictionary-style attacks—until it finds the correct one. That behavior defines what the tool is used for: cracking passwords through continuous guessing. Other options serve different security roles rather than cracking passwords. A firewall blocks or filters network traffic to prevent unauthorized access. A password manager securely stores and can generate strong passwords, helping you manage credentials rather than breaking into accounts. Antivirus detects and removes malware to protect the system, not to guess passwords.
