Which type of network topology has been focused primarily on alternative routing around cities and industrial areas?

The correct choice is associated with how a network can effectively manage traffic and ensure reliability in urban and industrial environments. In a topology focused on alternative routing, the aim is to provide multiple paths for data to travel, which increases resilience and efficiency.

Selecting this topology emphasizes the ability to reroute data effectively if one path encounters issues or congestion. This adaptability is critical in urban areas where there are numerous potential obstacles and varying traffic conditions.

This is particularly important in environments where high availability and low downtime are crucial, leading to a network that can adapt dynamically to changing conditions. Such adaptability can greatly improve performance, making it suitable for cities and industry-specific applications where conditions are not static.

The other network topologies, while beneficial in certain applications, do not inherently focus on alternative routing the way the correct choice does. Implementations like star topology, although useful for its centralized management, do not offer the same inherent resilience through multiple routing paths as seen in the selected alternative.
