Choose the option opposite in meaning to the underlined word or phrase. One of the students bought a plagiarised copy of the book.
Answer Details
The word opposite in meaning to "plagiarised" is "original".
"Plagiarised" means copied from someone else without giving proper credit. So, if one of the students bought a "plagiarised" copy of the book, it means they bought a copied version of the book. The opposite of this would be an "original" copy, which means the student bought the original, non-copied version of the book.
