Correct Answer: B
The command 'oam lsp-ping prefix 192.10.1.2/32' is used to send MPLS Echo Request packets to verify the reachability and state of the LSP (Label Switched Path). The use of the 'prefix' keyword here indicates that the MPLS Echo Request packets are sent using the LDP (Label Distribution Protocol) tunnel that is signaled for the prefix 192.10.1.2.
