Which of the following statements a), b) or c) is false? a. Dictionary comprehensions provide a convenient notation for quickly generating dictionaries, often by mapping one dictionary to another. b. The following code, which has a dictionary with unique values, reverses the key–value pairs: months2 = {number: name for name, number in months.items()} O. If the values in Part (b) were not unique, then the code would generate a ValueError. O d. All of the above statements are true.
