Show answer and explanation

Answer: C. Only conclusion III follows

• Answer: C
• Explanation: Let's analyze the Venn diagram intersections:
"All firewalls are encryptions" means the Firewall circle is completely inside the Encryption circle. "Some encryptions are protocols" means the Encryption and Protocol circles overlap. However, this overlap does not necessarily touch the Firewall circle, so Conclusion I ("Some firewalls are protocols") is not definitely true. "No protocol is a malware" means the Protocol and Malware circles are entirely separate.
