Solution

The correct option is B Upto next intermediate node is allocated before transmission of packet begins

Upto next intermediate node is allocated before transmission of packet begins In distance vector routing the path.

Distance-vector protocols update the routing tables of routers and determine the route on which a packet will be sent by the next hop which is the exit interface of the router and the IP address of the interface of the receiving router. Distance is a measure of the cost to reach a certain node.

Distance vector routing is a simple routing protocol used in packet-switched networks that utilizes distance to decide the best packet forwarding path. ... A hop is the trip that a packet takes from one router to another as it traverses a network on the way to its destination.

Packet switching is a method of grouping data which is transmitted over a digital network into packets. Packets are made of a header and a payload. Data in the header is used by networking hardware to direct the packet to its destination where the payload is extracted and used by application software.

Data-transmission term for a small bundle of data sent across a network (such as a LAN or Internet). A packet consists of a block of data bits plus control information that helps in its proper routing and reassembly into the original form at the receiving end.
