The option of defect in a book that has blank pages after annotations have been made

Question:
The questioner says: Honorable Shaykh, may Allah grant you success, I bought a book and wrote annotations in it. When I reached the middle of the book, I found that there were blank spaces in many of the pages. Does the option of defect apply to me?

Answer:
You have already used it. If you had not written in it, the option would have remained for you. Since you have used it and written in it, the seller can take it back, so the truth is upon him. Yes.
