The correct option that describes what a thesaurus is used for is B. Finding synonyms and antonyms of a word.

A thesaurus is a reference book or tool that organizes words into groups based on similarity in meaning. It provides a list of synonyms, which are words that have the same or similar meanings to the word you are looking up. So, if you want to find alternative words to use in your writing or to expand your vocabulary, a thesaurus is the perfect resource.

To use a thesaurus, you can follow these steps:

1. Identify the word you want to find synonyms for.
2. Open a physical or digital thesaurus.
3. Look up the word in alphabetical order.
4. Scan through the list of synonyms provided for your word.
5. Choose the synonyms that best fit the context or desired word usage.

On the other hand, if you were looking for the origins of a word, you would use an etymology dictionary or do some research on word origins. If you wanted to find the definition of a word, you would consult a dictionary. And for finding the pronunciation of a word, you can use an audio dictionary or pronunciation guide.
