Here are the options analyzed in turn, with attention to Python syntax and tuple immutability.
Option 1: None of them
This is the correct choice, because a tuple in Python is immutable; you cannot change its elements in place. The question asks to update the 3rd value to 'Z', but since tuples cannot be modified after creation, none of the listed update syntaxes will actually perform the desired mutation. Conceptually, you would need to construct a new tuple if you wanted a modified version, not change the existing one in place.
Option 2: tuple_two(2) = 'Z'
This uses parentheses in a way that resembles a function call, not indexing. In Python, parentheses with a number is not valid for accessing or updating tuple elements. Therefore, this is syntactically incorrect for selecting or mutating an element.
Option 3: tuple_two[2] = 'Z'
This uses 0-based indexing to target the third element, which is how you access items in a list or tuple. However, even if you retrieved the value, attempting to assign to an index of a tuple is illegal because tuples are immutable. This would raise a TypeError at runtime if executed.
Option 4: tuple_two{2} = 'Z'
This syntax uses curly braces in a way that is not valid Python for indexing or assignment. Curly braces have different meanings (e.g., sets or dict literals) in Python, but this particular form is invalid syntax for tuple element assignment and would cause a syntax error.
In summary, only None of them is a viable option for updating the 3rd element of the given tuple, given Python’s immutability of tuples and the invalidity of the other syntaxes.
