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

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

A) Because IMDb movie reviews are numerically encoded in the dataset bundled with Keras, to view their original text, you need to know the word to which each number corresponds.
B) Keras's IMDb dataset provides a dictionary that maps the words to their indexes. Each word's corresponding value is its frequency ranking among all the words in the entire set of reviews.
C) In the dictionary mentioned in Part (b) , the word with the ranking 1 is the most frequently occurring word (calculated by the Keras team from the dataset) , the word with ranking 2 is the second most frequently occurring word, and so on. Though the dictionary values begin with 1 as the most frequently occurring word, in each encoded review, the ranking values are offset by 3. So any review containing the most frequently occurring word will have the value 4 wherever that word appears in the review.
D) All of the above statements are true.
