You are requested to design a solution to handle a fallout scenario while communicating with an inventory system for resource allocation because there are no available ports for a product that was purchased. Identify a solution that would address this condition.
A. designing OSM to update the CRM system about the failure, so that the customer service representative (CSR) can decide whether to cancel the in-flight order or issue a new revision order to allocate new ports
B. cancelling the order in OSM and informing the customer that the request cannot be processed
C. reallocating the reserved ports in the inventory system and activating the requested ports in the activation system manually
D. suspending the in-flight order in OSM and manually creating a new order to create new ports in the inventory system
E. using the Task Web client to edit the order, manually changing the data received from the CRM system, and retrying the failed task for proper allocation of new ports
