What is the meaning of the relationship shown in the diagram below?

A . class B is the creator of class A
B . class A is dependent on class B
C . class B is dependent on class A
D . class A can be reached (torn class B

Answer: B

Explanation:

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.
