Final answer:
Option B, where the pharmacy is asked to compromise on medication delivery times, is an example of a major weakness of service-integrated structure.
Step-by-step explanation:
A major weakness of a service-integrated structure can be seen in option B. The pharmacy being asked to compromise on the times medications are delivered to the units is an example of a weakness because it compromises the efficiency and effectiveness of the service integration. When different units within an organization are not able to align their processes and strategies, it can lead to conflicts and inefficiencies, negatively impacting the overall service delivery.
