Final answer:
The architectural pattern developed from MVC to support applications with multiple agents and interactive requirements is PAC. It enables the management of complex systems by dividing functionality among agents with their own Presentation, Abstraction, and Control components.
Step-by-step explanation:
The answer to the question '_____ was developed from MVC to support the application requirement of multiple agents in addition to interactive requirements' is c. PAC (Presentation-Abstraction-Control). The PAC architectural pattern was developed as an enhancement of the Model-View-Controller (MVC) pattern to better suit the needs of complex applications involving multiple agents and interactive systems, where a simplistic MVC approach may not suffice. PAC provides a more structured approach that enables better separation of concerns and facilitates the support of multi-agent systems.
In PAC, the system is divided into agents, and each agent is responsible for a specific aspect of the application's functionality. These agents contain three components: Presentation, Abstraction, and Control. The Presentation component deals with the user interface, Abstraction represents the application's data, and Control acts as an intermediary that handles the communication between Presentation and Abstraction components, as well as with other agents.
PAC thereby helps in managing the complexity of applications that have various interactive parts and need to support concurrency and communication among different parts of the system. This makes PAC particularly useful in distributed systems or when building complex user interfaces that involve rich interactions among numerous components.
