Which of the following is not a correct method to create a DataFrame? A). `pd.DataFrame({'Name': ['A','B']})` B). `pd.DataFrame([('A', 10), ('B',20)], columns=['Name','Marks'])` C). `pd.DataFrame('Name', 'Marks')` D). `pd.DataFrame ([[1,2], [3,4]])`

The correct answer is `pd.DataFrame('Name', 'Marks')`. A DataFrame must be initialized using an array-like structure (like a list, dictionary, or another DataFrame). Option (C) `pd.DataFrame('Name', 'Marks')` attempts to pass two standard strings directly into the constructor without a proper data structure (like a list or dictionary), which will raise an error. Hence, it is not a correct method.
