Two systems have identical functionality but differ in architecture. System A uses a layered architecture, while System B uses a microservices architecture. Which of the following statements most accurately reflects the architectural trade-off between them?
  1. ASystem B boosts modularity and deployability, at the cost of higher inter-service communication overhead.
  2. BSystem A is easier to scale horizontally than System B.
  3. CBoth architectures ensure identical runtime performance under equal workloads.
  4. DSystem A has lower cohesion and higher coupling compared to System B.
