Which of the Following Statements A), B) or C) Is

Which of the following statements a) , b) or c) is false?

A) Dimensionality reduction in scikit-learn typically involves two steps-training the estimator with the dataset, then using the estimator to transform the data into the specified number of dimensions.
B) The steps mentioned in Part (a) can be performed separately with the TSNE methods fit and transform, or they can be performed in one statement using the fit_transform method, as in: In [5]: reduced_data = tsne.fit_transform(digits.data)
C) TSNE's fit_transform method takes some time to train the estimator then perform the reduction. When the method completes its task, it returns an array with the same number of rows as digits.data, but only the number of columns specified by the n_components argument when you created the estimator object. You can confirm this by checking reduced_data's shape.
D) All of the above statements are true.
