It’s B because loopguard helps prevent loops from nondesignated ports failing silently.

Is the loop on trunk ports? That would rule out D for sure.

Loopguard is the best fit here to stop loops, so B.

B imo, loopguard stops loops by blocking inconsistent ports before issues arise.

D. PortFast with BPDU guard is usually used on access ports to prevent loops caused by devices sending BPDUs. Since the question is about a Layer 2 loop, enabling BPDU guard can shut down ports that receive unexpected BPDUs, which helps fix loops caused by misconfigured devices. The other options either don't directly block loops or are more about spanning-tree optimizations than prevention.
