Which statement best describes the use of only actual parameters in a call statement?

The statement that the use of only actual parameters in a call simplifies the method invocation is correct because it highlights how actual parameters provide the specific values that the method will work with at runtime. When invoking a method, using actual parameters allows the programmer to pass real data directly into the method without the need for intermediary variables or step-by-step initialization.

This means the method can operate with the specific input provided in the call. For example, if a method takes in two integers as parameters, passing actual integers directly during the method call makes it clear what values are intended for use during the execution of that method. This simplicity is valuable as it leads to cleaner, more readable code and reduces the amount of code needed to prepare for the method call.

In contrast, defining a method, initializing it, or ensuring compilation relies on the method's structure, signature, and the presence of appropriate parameters but does not specifically relate to the simplicity of the invocation itself. Therefore, the approach of using actual parameters streamlines the process and enhances code readability and maintainability.
