Why each option

Dynamic routing protocols increase network availability and scalability while reducing administrative overhead compared to static routing.

Aincreased network security

Dynamic routing does not inherently increase network security; in fact, it can introduce security vulnerabilities if not properly secured with authentication and filtering.

Bdecreased network latency

While dynamic routing can find optimal paths, it does not inherently decrease network latency, which is primarily influenced by physical distance, link speeds, and congestion.

Cincreased network availabilityCorrect

Dynamic routing protocols automatically adapt to network topology changes, rerouting traffic around failures, which significantly increases network availability and resilience.

Dgreater network scalabilityCorrect

Dynamic routing protocols allow networks to scale more easily as new devices or subnets are added, as routes are automatically discovered and propagated, eliminating the need for manual configuration on every router.

Elower administrative overheadCorrect

For large or frequently changing networks, dynamic routing protocols drastically reduce the manual effort required to configure and maintain routing tables, leading to lower administrative overhead.
