An object’s . . . . . . . . include methods and events.

The correct answer is B. Behavior.

An object’s behavior is the set of actions that it can perform. These actions are defined by the object’s methods. Methods are functions that are associated with an object and can be called on that object.

For example, a Car object might have methods such as drive(), brake(), and turn(). These methods allow the Car object to perform the actions of driving, braking, and turning.

The other options are incorrect because:

• A. Attribute is a property of an object. For example, a Car object might have attributes such as color, make, and model.
• C. Instance is an object that is created from a class. For example, if Car is a class, then a Car object is an instance of the Car class.
• D. Method is a function that is associated with an object. For example, a Car object might have methods such as drive(), brake(), and turn().
