B is the answer. The glossary is just the definitions, thesaurus is not in a book and the table of contents gives events and when they occur not definitions. So, B, index is the correct answer.
Hiya!
The answer is
A the glossary.

The index is at the end of the book of tells the page numbers and topics and where to find them.

A thesaurus tells a little bit more about a specific word such as maybe it's synonyms and antonyms homophones Etc.

The table of content tells us where to turn to for information and chapter titles.

Hope This Helps! :)
