You are working on a program where you have an object named 'Invoice' that represents billing for a service. You want to write a method that calculates the total cost including taxes. If we want to call this method to perform its task, which of the following is the correct option?
Methods are actions that can be performed on objects. A method that calculates the total cost, including taxes, would likely take parameters or use internal variables and then return the calculated value. 'invoice.calculateTotal()' is the correct way to call a method named 'calculateTotal' for an object 'invoice'. The method name follows the object name separated by a dot, which indicates that 'calculateTotal' is a method belonging to the 'Invoice' object.
