Selected Answer: AD
A. tup[:]: This creates a shallow copy of the entire tuple. It is a valid action for a tuple, even if the tuple is empty. The result will be a new empty tuple. B. tup.append(0): Tuples in Python are immutable, meaning their elements cannot be modified after creation. Therefore, the append method, which is used to add elements to a list, is not applicable to tuples. Attempting to use append on a tuple will result in an AttributeError. C. tup[0]: This attempts to access the element at index 0 of the tuple. However, since the tuple is empty, this will result in an IndexError because there are no elements in the tuple. D. del tup: This deletes the entire tuple. This is a valid action and will remove the tuple from memory. So, the correct options are: A. tup[:] D. del tup
