Answer: C

Explanation:

Among the listed protocols, External Border Gateway Protocol (EBGP) provides the highest degree of scalability for an IP fabric underlay. EBGP is designed for inter-autonomous system routing and thus is well-suited to handle large-scale network environments with robustness and scalability. It is commonly used in data center fabrics due to its ability to efficiently manage routing information and scale with the network as it grows.
