Which of the Following Statements Is False

Which of the following statements is false?

A) The += augmented assignment statement can be used with strings and tuples, even though they're immutable.
B) In the following snippets, after the two assignments, tuple1 and tuple2 are two different copies of the same tuple object: In [1]: tuple1 = (10, 20, 30)
In [2]: tuple2 = tuple1
In [3]: tuple2
Out[3]: (10, 20, 30)
C) Concatenating the tuple (40, 50) to tuple1 from Part (b) , as in tuple1 += (40, 50)
Creates a new tuple, then assigns a reference to it to the variable tuple1-tuple2 still refers to the original tuple.
D) For a string or tuple, the item to the right of += must be a string or tuple, respectively-mixing types causes a xe "TypeError"TypeError.
