Answer» Adding an element to an existing tuple. Answer : (II) , (III) and (IV) Reason : 1. For part (II) - You can't concatenate different data types 2. For part (III) - Dictionaries and unordered data types so you can't slice them the way you can slice strings or tuples or lists 3. For part (IV) - Whenever you add an element to tuple, A new tuple is formed because Tuples are immutable data types |
