Which of the following statements is false?

a. With pass-by-value, the called function receives a copy of the argument’s value and works exclusively with that copy. Changes to the called function’s copy do not affect the original variable’s value in the caller.
b. With pass-by-reference, the called function can access the argument’s value in the caller directly and modify the value if it’s mutable.
c. Python arguments are always passed by value.
d. When a function call provides an argument, Python copies a reference to the argument object—not the object itself—into the corresponding parame-ter—functions often manipulate large objects—frequently copying them would consume large amounts of computer memory and significantly slow program performance.

c. Python arguments are always passed by value.
