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

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

A) In big data, samples can have hundreds, thousands or even millions of features.
B) To visualize a dataset with many features (that is, many dimensions) , you must first reduce the data to two or three dimensions. This requires a supervised machine learning technique called dimensionality reduction.
C) When you graph the resulting data after dimensionality reduction, you might see patterns in the data that will help you choose the most appropriate machine learning algorithms to use. For example, if the visualization contains clusters of points, it might indicate that there are distinct classes of information within the dataset.
D) All of the above statements are true.
