Q: When an instance of a class is present inside a method, its behaviour is determined by  

In object-oriented programming, a class is a template for creating objects.
An object is an instance of a class, and it has the same behavior as defined by the class.
The class defines the properties and methods that the object will have, and the object is created based on that template.
All objects of the same class have the same behavior, but they can have different property values.
For example, you could have a class called "Dog" that defines the behavior of a dog, such as barking and wagging its tail.
You could then create multiple objects of the "Dog" class, each representing a different individual dog with its own unique characteristics, such as breed and name.
