An entity that has state and behaviour is known as an object e.g. chair, bike, marker, pen, table, car etc. It can be physical or logical (tangible and intangible). The example of the intangible object is the banking system.
An object has three characteristics:
State: represents data (value) of an object.
Behaviour: represents the behaviour (functionality) of an object such as deposit, withdraw etc.
Identity: Object identity is typically implemented via a unique ID. The value of the ID is not visible to the external user. But, it is used internally by the JVM to identify each object uniquely.

Associated with Objects
Objects in programming are instances of classes that encapsulate data and behavior. They are the building blocks of object-oriented programming and are used to represent real-world entities or concepts.
In the context of object-oriented programming, several concepts are associated with objects. These concepts include state, behavior, and identity.
State:
- The state of an object refers to the current values of its attributes or properties.
- Attributes or properties represent the data associated with the object.
- For example, if we have an object representing a car, its state may include attributes like the car's color, model, and current speed.
- The state of an object can change over time as the object interacts with its environment or as its behavior is executed.
Behavior:
- The behavior of an object refers to the actions or operations that the object can perform.
- Behaviors are typically defined by methods or functions associated with the object.
- For example, a car object may have behaviors such as accelerating, braking, or changing gears.
- The behavior of an object is determined by its class, which defines the methods or functions that can be called on objects of that class.
Identity:
- The identity of an object refers to its unique existence within a program.
- Each object has a unique identity that distinguishes it from other objects.
- Even if two objects have the same state and behavior, they are still considered distinct objects with different identities.
- The identity of an object is typically represented by a memory address or a unique identifier associated with the object.
Summary:
Objects in programming are associated with state, behavior, and identity. The state of an object refers to its current values of attributes, behavior refers to the actions or operations the object can perform, and identity refers to its uniqueness within a program. Therefore, the correct answer is option 'D' - all of the above.
