The correct answer is B. Hub-and-spoke. A hub-and-spoke design sends all branch and cloud traffic into the central hub (your data center) for inspection, then back out, meeting the requirement for centralized egress and security inspection.

Explanation
A hub-and-spoke design sends all branch and cloud traffic into the central hub (your data center) for inspection, then back out, meeting the requirement for centralized egress and security inspection. By deploying multiple hub nodes and using dynamic path selection, you also achieve redundancy without losing the centralized control plane.
