The concept of coupling between building blocks is crucial in software architecture, and the iSAQB SOFTWARE ARCHITECTURE - FOUNDATION LEVEL provides guidance on this topic. Here's an analysis of the statements based on the curriculum:
A) A high degree of coupling of a building block reduces its reusability: This is correct. High coupling means that a building block is heavily dependent on other components, which can limit its ability to be reused in different contexts1.
B) Low coupling of a building block improves the ability to meet functional requirements: This statement is incorrect. While low coupling can contribute to a more maintainable and flexible architecture, it does not directly improve the ability to meet functional requirements1.
C) Low cohesion often leads to high coupling: This is correct. Cohesion refers to how closely related the responsibilities of a module are. Low cohesion can result in modules that perform a wide range of actions, which often leads to higher coupling with many other modules1.
D) Loose coupling often leads to less effort for making changes: This is correct. Loose coupling allows for easier modification of a system with minimal impact on other components, thus reducing the effort required for changes1.
E) For call dependencies, the degree of coupling is independent of the direction of the call: This statement is incorrect. The degree of coupling can be affected by the direction of the call, as it determines which module controls the interaction1.
F) In object-oriented programming languages, inheritance reduces coupling: This statement is incorrect.
Inheritance can actually increase coupling because it creates a direct dependency between the superclass and the subclass1.
These insights are aligned with the principles outlined in the iSAQB SOFTWARE ARCHITECTURE - FOUNDATION LEVEL curriculum, which emphasizes the importance of understanding and managing coupling for effective software architecture design1.

Explanation:
For a building block, the characteristics visible only in the whitebox view are:
* Code structure of the building block (D)
* Algorithms used in the building block (E)
* Implementation details for the security requirements of the building blocks (G) The blackbox view suffices for:
* Public interfaces of the building block (A)
* Test coverage based on unit tests for sub building blocks contained in the building block (B)
* Test coverage based on integration tests
* Security requirements of the building blocks (F)
In software architecture, the whitebox view reveals the internal workings of a building block, including its code structure, algorithms, and specific implementation details1. This view is essential when the internal structure and behavior of the component need to be understood or modified.
On the other hand, the blackbox view treats the building block as an opaque entity, focusing on its exposed interfaces and observable behaviors without revealing its internal structure2. This view is sufficient for understanding what the building block does from an external perspective, such as its public interfaces and how well it performs its functions as determined by testing.
Here's a breakdown of the characteristics:
* Whitebox View:
* Code Structure (D): This includes the organization of code within the building block, such as classes, interfaces, and other components.
* Algorithms (E): The specific algorithms used within the building block to perform its functions.
* Implementation Details for Security (G): The actual code and strategies used to fulfill the security requirements.
* Blackbox View:
* Public Interfaces (A): The interfaces that are exposed to other building blocks or systems.
* Test Coverage for Sub Building Blocks (B): The extent to which the unit tests cover the sub-components within the building block.
* Test Coverage for Integration Tests : The coverage of tests that verify the interactions between building blocks.
* Security Requirements (F): The security objectives and criteria that the building block must meet.
