$Question 29 What is the output of the following? ```python car = { "brand": "Ford", "model": "Mustang", "year": 1964 } x = car.keys() print(x) ``` - ⬜ dict_keys(['Ford', 'Mustang', '1964']) - ⬜ { "brand": "Ford", "model": "Mustang", "year": 1964 } - ⬜ SyntaxError - ⬜ dict_keys(['brand', 'model', 'year']) This question presents a Python dictionary named `car`, which contains three key-value pairs: `"brand": "Ford"`, `"model": "Mustang"`, and `"year": 1964`. The method `car.keys()` is being called to retrieve all the keys in the dictionary, and the result is assigned to the variable `x`. The `print(x)` statement will output the keys of the dictionary. The correct answer in this context is: - dict_keys(['brand', 'model', 'year'])$
