Explanation

Immutable backups are the most appropriate response to a sophisticated ransomware threat because they cannot be encrypted, deleted, or altered by ransomware. They ensure that even if systems are compromised, the organization can restore data without paying a ransom. Deploying a new antimalware solution (B) may not detect novel/zero-day ransomware variants. Upgrading a firewall (C) helps with perimeter defense but does not address recovery once ransomware is already inside. Cybersecurity insurance (D) offsets financial costs but does not prevent data loss or downtime. Immutable backups directly neutralize the core impact of ransomware - loss of access to data.
