In UML, when you need to reference an element from another package while inside a different package, you use the qualified name. A qualified name includes the package name followed by two colons and then the element name. This ensures that the reference is clear and unambiguous, especially when different packages may have elements with the same name.

The correct syntax for referring to elementOneof PackageP1from inside PackageP2isP1::One, where::is the scope resolution operator used to separate the package name from the element name.

Therefore, the correct answer is:

D. P1::One

In UML, when a class diagram shows an operation with a parameter that has a multiplicity of [0..1], it indicates that the parameter is optional. The range [0..1] means that the parameter can have 0 or 1 occurrence. This does not mean it accepts a collection, nor does it specify the values it accepts (it specifies how many times the parameter can occur).

The correct interpretation of the parameterpar1 : Integer [0..1]is:

A. It is optional.

B is incorrect because the multiplicity [0..1] does not mean a collection of items; rather, it signifies that the parameter can be omitted or present, but not multiple times. C is incorrect because the multiplicity [0..1] does not constrain the values to 0 or 1; it refers to the number of instances of the parameter. D is incorrect because [0..1] is not a range of values but a range of occurrences or instances of the parameter.

Therefore, the correct answer is:

A. It is optional.
