easy🧠 Conceptual Q1 of Q15
Step-by-Step Solution
Solution:
Step 1: Understand the role of Entities layer
The Entities layer defines core business objects and interfaces/abstractions without implementation details.Step 2: Differentiate from other layers
Use Cases layer contains application-specific business rules and orchestrates interactions; Interface Adapters convert data formats; Frameworks and Drivers handle external tools.Final Answer:
Entities layer -> Option CQuick Check:
Layer defining interfaces and abstractions = Entities layer [OK]
Quick Trick: Entities layer defines interfaces and abstractions, not Use Cases or Adapters [OK]
