Which of the following statements is false? O You can always pass an instance of a subclass to a parameter of its superclass type. This feature is known as polymorphism. The compiler finds a matching method according to parameter type, number of parameters, and order of the parameters at compile time. Dynamic binding can apply to instance methods.
