Correct Answer: C
To determine which port will be in the blocking state, we need to understand how the Spanning Tree Protocol (STP) operates. SWA has the lowest Bridge ID (4096:0001-0203-04AA), so it will be the root bridge. Ports on the root bridge are always in the forwarding state. Between SWB and SWC, both have the same bridge priority, but SWC has a higher MAC address (04CC) compared to SWB (04BB). Therefore, SWC will have its port G0/0/1 blocked as it forms a loop-free topology by preventing the connection between SWC and SWB from being active simultaneously.
