Answer is Right!
Answer is Wrong!
The correct answer is D. Everyone must read this book.
The other options are incorrect because they do not express the same level of necessity as the correct option. Option A, This book should be read by everyone, expresses a recommendation, but not a requirement. Option B, This book has to be red by everyone, is grammatically incorrect. Option C, This book is to be read by everyone, is also grammatically incorrect, and it does not express the same level of urgency as the correct option.
The correct option, Everyone must read this book, expresses a strong requirement that everyone read the book. This could be because the book is very important, or because it is required reading for a class or job.
