Explanation

Ransomware encrypts an organization's data and demands payment for decryption. The most effective counter is having tested, reliable, and isolated backups - they allow restoration without paying the ransom. Automatic quarantine (A) aids containment but doesn't recover data. Communication plans (B) are important during response but don't mitigate the attack itself. Strong passwords (C) may reduce initial access vectors but do not address data recovery once ransomware is deployed.
