Which of the following routing protocols relies on hop count as its ONLY metric?
The correct answer is D. RIP. RIP (Routing Information Protocol) is the only major routing protocol that uses hop count as its sole metric for path selection, with a maximum of 15 hops.

Why each option
RIP (Routing Information Protocol) is the only major routing protocol that uses hop count as its sole metric for path selection, with a maximum of 15 hops.
BGP uses a complex set of path attributes including AS-PATH, LOCAL_PREF, and MED rather than hop count.
EIGRP uses a composite metric calculated from bandwidth, delay, load, and reliability - not hop count alone.
OSPF uses a cost metric derived from interface bandwidth, not hop count.
RIP selects routes exclusively based on hop count - the number of routers a packet must traverse to reach the destination. It does not consider bandwidth, delay, or any other factor, and treats any destination beyond 15 hops as unreachable. This simplistic single-metric design is RIP's defining characteristic.
