The correct answer is B. Distance Vector Algorithm (DVA).
Explanation: BGP is classified as a path vector protocol, which is a type of distance vector routing protocol. Unlike traditional distance vector protocols that share the costs of paths, BGP shares information about entire paths and avoids routing loops by maintaining a list of autonomous systems a route passes through. Although BGP is an Exterior Gateway Protocol (EGP) used to exchange routing information between different autonomous systems, it uses the principles of distance vector algorithms in determining the best path for data transmission.
