Selected Answer: C

From the traceroute, you can see the packets make it as far as the server segment firewall (192.168.4.1) and then start timing out. Since all other users can reach the database server successfully, it suggests the server segment firewall is missing (or dropping) traffic from the development subnet. Therefore, C is the most likely cause.
