Final answer:
Routing protocols like OSPF, RIP, and BGP are used to determine the best path for data in a network, while routable protocols such as IP are used to send user data through established paths.
Step-by-step explanation:
The question pertains to the differences between routing protocols and routable protocols. Routing protocols are used in networks to determine the best path for data packets to travel from their source to their destination. Examples of routing protocols include OSPF (Open Shortest Path First), RIP (Routing Information Protocol), and BGP (Border Gateway Protocol). On the other hand, routable protocols are protocols that can be used to send user data through an established network path and are designed to carry user traffic. A key representative of a routable protocol is IP (Internet Protocol), which is tasked with addressing and routing packets between network nodes.
To directly answer the student's question: OSPF is a routing protocol, and IP is a routable protocol. This is the correct statement that expresses the differences between routing and routable protocols. Therefore, the correct option is 'OSPF is a routing protocol, IP is a routable protocol'.
Complete question is as follows :
Which of the following statements most closely expresses the differences in routing and routable protocols?
IP is a routing protocol, whereas RIP is a routable protocol
OSPF is routing protocol, IP is a routable protocol
BGP is used as routable protocol, RIP is routing protocol
Routable protocols are used to define best path from point A to point B, routing protocols are used to transport data
