Maybe D, since MPLS tags packets just after the MAC header but before the IP header, which fits between Data Link and Network layers. That’s the common understanding for where MPLS lives in OSI.

D, because MPLS operates below the network layer, not above it.

Option D makes sense since MPLS acts like a shim header right after Layer 2, so it fits neatly between the data link and network layers. It’s definitely not anywhere near Layers 5 or 6.

D imo. MPLS labeling happens after the data link layer but before the network layer processes the packet, so between Layer 2 and 3 fits best here.

C imo. MPLS works by adding labels right after the IP header, so it fits best between Layer 3 (network) and Layer 4 (transport). That’s where routing decisions are made, and MPLS labels help with forwarding. Option D placing it between Layer 2 and 3 doesn’t feel right since that’s more about Ethernet and IP boundary, not labeling.
