The correct option is Extensions for order system integration, data stores for knowledge base retrieval, functions for case creation, plugins for translation.

This mapping places external order platform connectivity with Extensions. These let the agent securely call third party or internal APIs and fetch a customer’s purchase history which is exactly what an order management integration requires.

Grounding answers on product and policy content belongs with data stores. Data stores enable retrieval augmented generation so the agent can search and cite enterprise knowledge bases and return accurate responses.

Carrying out actions such as creating a support case fits functions. With function calling the model selects the right tool and sends structured parameters so your backend can create the case and return results to the conversation.

Adding new skills like real time language translation is well suited to plugins. These provide ready made capabilities that can be enabled for the agent so the team can add translation without building custom logic.

Functions for all four needs is incorrect because functions are great for action execution yet they are not the right fit for retrieval over large knowledge bases or for direct external system integration and they are not the most straightforward way to add new packaged skills like translation.

Plugins for order system integration, data stores for knowledge base search, extensions for case creation, functions for translation is incorrect because external system connectivity belongs with Extensions and action execution like case creation belongs with functions. Translation is better added as a packaged capability through plugins rather than as a custom function.

Data stores for everything related to information and capability and extensions for any outside connection is incorrect because data stores are for retrieval and grounding rather than for executing actions or adding skills like translation. You still need functions for actions and plugins for packaged capabilities.
