How does LDP operate in an MPLS network?

BWhen an adjacent LSR receives LDP discovery messages. TCP two-way handshake ensures that the LDP session has unidirectional connectivity.

Option C seems the most comprehensive description of how LDP operates in an MPLS network. The peers establish the session and maintain it through message exchanges.
