C.    LDP uses downstream unsolicited mode by default. An LSR advertises label mappings to peers without being asked
D.    LDP uses UDP-confirmed messages to establish sessions between PE ingress and egress routers. The UDP messages encode the label information for each LSP and sub-LSP link

Answer: C
