Refer to the exhibit. Which routing protocol has the best administrative distance?
The correct answer is B. EIGRP. Administrative distance is the feature that routers use to select the best path when there are two or more different routes to the same destination from two different routing protocols. A lower numerical value is preferred. Note on EIGRP: While the letter "R" typically stands for

Explanation
Administrative distance is the feature that routers use to select the best path when there are two or more different routes to the same destination from two different routing protocols. A lower numerical value is preferred. Note on EIGRP: While the letter "R" typically stands for RIP (AD 120), in this specific Cisco output, the brackets show [90/1]. Since the AD is 90, this indicates EIGRP (internal). If it were RIP, the first number in the brackets would be 120. Note on "Connected": While "Connected" (AD 0) is technically the "best" or most trusted, it is generally categorized as a route type rather than a dynamic routing protocol. In the context of "Which routing protocol," we look at EIGRP, OSPF, and RIP.
