[ 0, 0, 0, 0, 1, 0, 0, 0, 1, 41]])
Which of the following statements is false?

• A) The correct predictions are shown on the diagonal from top-left to bottom-right-this is called the principal diagonal.
• B) The nonzero values that are not on the principal diagonal indicate incorrect predictions (that is, misses).
• C) Each row represents one distinct class-that is, one of the digits 0-9.
• D) The columns within a row specify how many of the test samples were classified incorrectly into each distinct class 0-9.
