What does an object in programming contain?

  1. References to other objects only

  2. State, behavior and identity

  3. Functions or methods only

  4. Static data only

The correct answer is: State, behavior and identity

An object in programming contains both state and behavior, as well as a unique identity. State refers to the data or variables that an object holds and behavior refers to the actions or functions that the object can perform. A reference to other objects may be included in an object's state, but it is not the only thing an object contains. While an object may have functions or methods, it is not limited to just functions or methods. Similarly, while an object may contain static data, it is not limited to just static data. Therefore, the correct answer is B as it encapsulates all three components of an object.
