Comprehensive and Detailed Step-by-Step Explanation:

Recovering from ransomware attacks often depends on having a robust data recovery strategy:

A. Automatic quarantine of systems: This can limit the spread of ransomware but does not address recovery.

B. Thorough communication plans: Communication is important during incidents but does not directly mitigate ransomware.

C. Effective backup plans and processes: This is the BEST option because having backups ensures that encrypted data can be restored, minimizing downtime and data loss.

D. Strong password requirements: This helps prevent unauthorized access but is not sufficient to combat ransomware once it has entered the system.
