Question

Quizplus · Accepted Answer

Parameter variables in a hand-tracing method are determined by the arguments supplied in the code that invokes the method. This means that the values of the parameters can be different each time the method is called, depending on the arguments passed. Therefore, option D is the right choice. Options A and B are incorrect as the values of the parameters may vary based on the arguments passed. Option C is incorrect as having missing or undetermined parameter values in a method is an undesirable scenario.
