Explanation

Mesh networks inherently create redundant paths that risk infinite packet loops, so they rely on TTL (Time To Live) and duplicate frame number detection as built-in loop-breaking mechanisms. TTL works by embedding a hop counter in each packet that decrements at every node - when it hits zero, the packet is discarded, preventing endless circulation. Duplicate frame detection assigns sequence numbers to frames; any node that receives a frame with a sequence number it has already processed simply drops it, stopping re-propagation at the source.

Why A (STP) and D (MSTP) are wrong: Spanning Tree Protocol and Multiple Spanning Tree Protocol are loop-prevention mechanisms designed for traditional wired Ethernet/switched networks. They operate by blocking redundant switch ports to create a loop-free logical topology - they are external layer-2 protocols, not internal mechanisms native to mesh architecture.

Memory tip: Think "TD breaks the mesh" - TTL kills packets that wander too long, and Duplicate detection kills packets seen before. STP/MSTP are for switches, not mesh.
