Select the most appropriate option to fill in the blank.
This is the ___________ book that I have read till now.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. most interesting.
The blank is filled with 'most interesting' because it is comparing this book to all the other books. When comparing more than two things, the superlative form of the adjective is used (e.g., 'most interesting,' 'tallest,' 'fastest').
In this sentence, the superlative form 'most interesting' is used to express that out of all the books, this one stands out as the highest in terms of interest.
