Final answer:
The data store in the repository architecture is passive, and the clients are active. The data store responds to actions initiated by the clients but does not initiate actions itself.
Step-by-step explanation:
The question is asking about the characteristics of components within a repository architecture. In the context of such a system, the data store is typically characterized as passive, meaning it operates only when prompted by another component and doesn't initiate actions on its own. On the other side, clients of the data store are described as active, indicating that they initiate communication with the data store to send requests or retrieve data. Clients perform actions such as querying or updating the data, which the passive data store responds to accordingly.
Therefore, the correct answer to the question is: c. passive/active. The data store in the repository architecture is passive, and clients of the data store are active.
