It is important that your book review contains:

The correct answer is: Your opinion of the book

The correct answer is "All the above".
An ideal book review should begin with the introduction of the book and its author, followed by briefly discussing the content of the book, the critical appreciation of that text with the help of background information, and the reviewer's opinion at the end. It should also have vivid description and catchy words to grab the attention of the reader and create a long-lasting impact. Since all the three options given are necessary for a book review, the correct answer is "All the above".
