New client components can be easily added in
Answer: C
New clients are easily added in a Data Centered Architecture.
In a data-centred (repository) architecture a central data store sits at the core, and client components access it independently. Because clients do not talk to each other directly, new clients can be added, and existing ones changed, without affecting the others. Pressman notes this integrability as the style's main advantage.
Data flow (pipe and filter) architecture chains transformations, call and return architecture builds a hierarchy of calls, and layered architecture stacks services. In each, adding a component means changing its neighbours.
