Choose the correct answer:Consider the following UML diagram fragments:The letters X and Y are placeholders.

The question is about identifying the correct placeholders X and Y in a UML diagram fragment related to cattle reproduction behavior. The correct answer is option E, where X is “natural::Reproduction_behav” and Y is “assisted::Reproduction_behav”. In UML, the “::” notation is used to indicate a namespace or a package. In this context, it separates the types of reproduction behaviors (natural and assisted) from the behavior itself (Reproduction_behav). This naming convention aligns with UML naming standards for clarity and specificity.
