What is true about the unbind () method?

Option B is true because the unbind() method is invoked from within a widget’s object 1.

Option D is true because the unbind() method needs the event name as an argument 1.

The unbind() method in Tkinter is used to remove a binding between an event and a function. It can be invoked from within a widget's object when a binding is no longer needed. The method requires the event name as an argument to remove the binding for that specific event. For example:

button = tk.Button(root, text="Click me")

button.bind("", callback_function) # bind left mouse click event to callback_function

button.unbind("") # remove the binding for the left mouse click event
