The correct answer is that virtual networks from different subscriptions can indeed link to the same Azure DDoS protection plan. This feature allows organizations with multiple subscriptions to manage their DDoS protection centrally and efficiently without the need to configure separate protection plans for each subscription's virtual network.

This flexibility is essential for large organizations or enterprises that may have multiple departments or projects operating under different subscriptions but still require comprehensive DDoS protection for all their resources. By enabling various subscriptions to share a DDoS protection plan, Azure helps simplify management and potentially lower costs associated with DDoS protection.

Other options imply limitations that are not accurate. For instance, suggesting that it's only applicable if the networks are in the same region restricts the functionality that Azure provides, as DDoS protection plans can span across regions. Similarly, indicating that only enterprise subscriptions can link to the DDoS protection plan overlooks the fact that any type of subscription can utilize this feature.
