  Explanation/Reference:

  The code snippet that you have sent is defining and calling a function in Python. The code is as follows:

  def runner(brand, model, year): return (brand, model, year) print(runner("Fermi"))

  The code starts with defining a function called "runner" with three parameters: "brand", "model", and "year". The function returns a tuple with the values of the parameters. A tuple is a data type in Python that can store multiple values in an

  ordered and immutable way. A tuple is created by using parentheses and separating the values with commas. For example, (1, 2, 3) is a tuple with three values.

  Then, the code calls the function "runner" with the value "Fermi" for the "brand" parameter and prints the result. However, the function expects three arguments, but only one is given. This will cause a TypeError exception, which is an error

  that occurs when a function or operation receives an argument that has the wrong type or number. The code does not handle the exception, and therefore it will terminate with an error message. However, if the code had handled the

  exception, or if the function had used default values for the missing parameters, the expected output of the code would be ('Fermi ', `2021', `False'). This is because the function returns a tuple with the values of the parameters, and the print

  function displays the tuple to the screen. Therefore, the correct answer is D.

  ('Fermi ', `2021', `False').
