B - Linux systems often have a variety of services running on different ports, which can make it challenging to determine the exact OS version based on open ports alone

Port 139 (netbios-ssn): This port is commonly used by Windows machines for NetBIOS over TCP/IP (NBT) communication.

Port 139 (netbios-ssn): This port is commonly used by Windows machines for NetBIOS over TCP/IP (NBT) communication. Port 445 (not shown): Although not explicitly shown in the results, it's likely that port 445 is also open, as it's often used together with port 139 for SMB (Server Message Block) communication in Windows environments. MAC Address: The MAC address (00:00:48:0D:EE:89) is within the range assigned to Microsoft Corporation, which further suggests that the host is a Windows machine. While it's possible for other operating systems or devices to have these ports open, the combination of these factors makes it most likely that the target machine is running a Windows operating system.
