by
A. When resources (time and budget) are over
B. When some coverage is reached
C. When quality criterion is reached
D. Testing never ends

B. Interaction diagrams are good at designing part or all of one use case’s functionality across multiple objects
C. Interaction diagrams allow the analyst to show iteration and conditional execution for messaging between objects
D. All of the mentioned
✅ The correct answer is option D.
