Which component acts as a coordinator between decoupages?

• A. Gemma
• B. Subassembly
• C. Periodic Task
• D. Leader

Answer: (D)

Coordination across decoupled components requires a central coordinating entity that can observe overall progress, make decisions, and dispatch commands to keep all parts in sync. The Leader fits this role by orchestrating interactions between the independent modules, issuing the right actions at the right times, and maintaining a consistent global state so the system works as a cohesive whole. It handles sequencing, resolves conflicts, and broadcasts status so each decoupled piece knows what to do next.

Other options don’t perform that coordinating authority. A subassembly is a self-contained unit that executes its own tasks but doesn’t arbitrate or synchronize multiple decoupled parts. A periodic task provides timing to trigger actions at regular intervals, but it doesn’t manage cross-component coordination. Gemma isn’t a recognized coordinating role in this context, so it wouldn’t fulfill the function of aligning multiple decoupled components.
