your answer is B) The book, tom sawyer, is full of entertaining and vivid characters.
The answer I am pretty sure must be B
The sentence with the incorrectly punctuated appositive is B. In this sentence, the appositive 'Tom Sawyer' is essential information and should not be set off by commas. The correct punctuation would be 'The book Tom Sawyer is full of entertaining and vivid characters.'
