Answer:
d) static
Step-by-step explanation:
static methods are basically global, but the class that originated them must also be static.
you can use a static method without having to instantiate a new object for the class variable, for instance, let's say there are 2 classes (Car and Airplane). Car has a non-static method called "drive()" and Airplane has a static method called "fly()"
If you want to call the method from Car, you'd have to do:
Car polo = new Car();
polo.drive();
If you want to call the method from Airplane, you'd have to call it directly from the class:
Airplane.fly();
