Answer : Option D
Explanation :
The primary purpose of a destroy function is to centralize the responsibility for cleaning up anything that the object has done that will:
1. Prevent its reference count from dropping to 0 (for example, removing problematic event listeners and callbacks and unregistering from any services).
2. Consume unnecessary CPU cycles, such as intervals or animations.
