Show Suggested Answer

Suggested Answer: B

In UML 2, the dashed arrow with an open arrowhead represents a dependency relationship. In the context of class diagrams, a dependency relationship indicates that changes to one class (the independent class) may cause changes in the other class (the dependent class). The direction of the arrow specifies which class is dependent on which. In the given diagram, the arrow points from class A to class B, which means that class A is dependent on class B. This could manifest as class A using some services or functions of class B, for example.

Wait, can someone explain how A can reach B? Sounds odd.

I think it's actually class B that's dependent on class A!

Definitely A is the creator of B, no doubt!

Class A is dependent on class B, right?

I’m leaning towards C, but I can't recall if it was specifically about one class being dependent on another or something else.

I feel like I might be mixing up the terms. Wasn't there something about creators and dependencies in the study materials?

I remember a practice question that had a similar diagram, and I think it was about how one class relies on another. Maybe it's B?

I think this might be about dependency relationships, but I'm not entirely sure if it's A or B.

The key here is to look at the direction of the arrow. It's pointing from class B to class A, so that means class B is dependent on class A. I'm pretty confident that B is the right answer.

I'm a little confused by the wording of the options. "Class A is dependent on class B" - does that mean class A needs class B to function? Or is it the other way around?

Okay, I think I've got this. The arrow indicates that class B is dependent on class A, so the correct answer must be B.

This diagram looks like it's showing some kind of relationship between two classes, but I'm not sure exactly what it means. I'll need to think through the options carefully.
