If return statement is not used inside the function, the function will return:0 pointsNone0NullArbitary value

The correct answer is None.

In Python, if a function does not explicitly return a value using the return statement, it returns None by default. This means that if a function is called and there is no return statement, the output of that function will be None, which is a special constant in Python indicating "no value" or "nothing."

Here is an example for clarity:

def my_function():
    x = 5 + 3  # This function does not return anything

result = my_function()
print(result)  # Output will be None

In the example, my_function performs a calculation but does not use a return statement, so it implicitly returns None.
