Explanation

EoMPLS (Ethernet over MPLS), referenced here as 'eoEMPLS' (C), is a pseudowire technology that extends Layer 2 Ethernet frames across an MPLS backbone network. It encapsulates Ethernet frames in MPLS labels, allowing geographically separated sites to appear as if they are on the same Layer 2 broadcast domain, even though the underlying transport is a private MPLS network. MPLS inherently supports multipath load balancing via Equal-Cost Multi-Path (ECMP) across label-switched paths. Plain MPLS (A) is the underlying transport layer but does not itself provide L2 Ethernet extension. VPLS (B) is also an Ethernet L2 over MPLS service, but it provides multipoint-to-multipoint L2 VPN (full mesh), whereas EoMPLS provides point-to-point pseudowires. The question's context of extending Ethernet into a private network with multipath aligns with EoMPLS.
