C)reverse path check
D)spanning tree protocol

Split horizon is the Layer 3 technology employed by distance-vector routing protocols in which a router knows which of its interfaces a routing update and will not retransmit, or advertise, that same update on the same interface. This helps avoid loops in the network topology. Round robin is a load-balancing technique, reverse path check is a security measure, and spanning tree protocol is a Layer 2 technology used to prevent loops in bridged networks.
