best

Answer 2

This is the better of the two books.

• Since the sentence is making a comparison between two objects i.e., two books here, the comparative degree of the adjective will be inserted here.
• The comparison will be made by using 'better' as it is the relevant form of the adjective 'good'.
• The sentence means that this book is better than the other one.
• So, 'better' is the correct word.
