Choose the correct answer:What is the difference between a ValueSpecificattonActlon and a CreateObjectAction?

The difference between ValueSpecificationAction and CreateObjectAction in UML is fundamental to the kinds of results they produce:

A.Incorrect, as there is a fundamental difference between the outputs of these two actions.

B.Correct. A ValueSpecificationAction evaluates to a value but does not produce instances of Classifiers, whereas a CreateObjectAction is specifically designed to instantiate classifiers.

C.Incorrect, because it reverses the capabilities of the two actions.

D.Also incorrect, because it provides the wrong association of features with actions.

References:

UML Specification: Action section, where both ValueSpecificationAction and CreateObjectAction are defined.

Further clarifications on these actions are provided in the UML 2.5 Documentation, especially in parts discussing Actions and Activities.
