My understanding is that B implies that there is no firewall nor proxy between the PC and the internet ("direct access"), which would indeed be the biggest problem. The formulation of C is unclear. What does "Firewall access" mean? It does not sound like direct external access.

Agree C is correct. Options A, B, and D also represent security concerns, but they are typically less severe compared to direct firewall access from the Internet to the internal network.
