AThe LAN is a single non-redundant network and the partitioned CAN is a dual redundant network, with both networks being interconnected.

BThe LAN is a dual redundant network and the partitioned CAN is also a dual redundant network, with no interconnectivity between the two networks.

CThe LAN is a dual redundant network and the partitioned CAN is also a dual redundant network, with both networks being interconnected.

DThe LAN is a single non-redundant network and the partitioned CAN is a dual redundant network, with no interconnectivity between the two networks.

AI Explanation

The correct answer is C. The LAN is a dual redundant network and the partitioned CAN is also a dual redundant network, with both networks being interconnected. This is the correct answer because the illustrated block diagram shows a distributed automation system with a dual redundant LAN and a dual redundant partitioned CAN, and these two networks are interconnected. This architecture provides redundancy and resilience in the system's communication networks. The other answer choices are incorrect because they do not accurately describe the network architecture shown in the illustration. Option A and D incorrectly state that the LAN is a single non-redundant network, and option B incorrectly states that the two networks are not interconnected.
