Which set of conditions comprises a successful ping attempt between two connected routers configured with IP addresses on the same subnet?

This option is incorrect because it states the destination host receives an echo reply from the source, which is backward; the destination sends the reply.

This option only describes the destination receiving an echo request, which is only half of the successful ping process and does not confirm the destination's ability to respond or the source's ability to receive the reply.

This option is incorrect for the same reason as A, stating the destination receives an echo reply from the source, which is reversed.

While this option correctly outlines the initial stages of a ping, with the destination receiving a request and the source receiving a reply, the truncated statement may lack the full, precise description of the complete two-way ICMP exchange necessary for a successful ping, as implied by option E being the sole correct choice.

A successful ping involves a complete round trip: the source host sends an ICMP Echo Request, the destination host receives it and processes it, and then the destination host sends an ICMP Echo Reply, which the source host successfully receives. This full exchange confirms end-to-end reachability and responsiveness.
