I disagree, I think it's D. The network can handle two link faults without disrupting the service, which is crucial for resilience.

Definitely C. Look at those demand routings - they're designed to minimize latency, not maximize protection or cost savings.

I'm not sure, but I think it could also be for 1+1 protection.

I agree with Jesusa. The demand routing seems to have redundancy for fault tolerance.
