• Chose B1

  The correct answer is: B. Presentation, application, and data processing ✅ Explanation: Three-tier architecture divides an application into three logical layers: Presentation layer — User interface. Application (logic) layer — Business logic and processing. Data layer — Data storage and management. This separation improves scalability, maintainability, and flexibility

• Chose B2

  The common three-tier design uses presentation, application, and data. In a website, the presentation tier is the front-end or the elements that the user interacts with. The data tier includes data storage. The application tier sits between the presentation and data tiers; it retrieves and processes the data and sends it to the front-end.
