Which one of the following is not a form of literature for children ?

The correct answer is Thesaurus.

Step-by-step Explanation:

1. Understanding Children's Literature:
Children's literature includes books, stories, poems, and plays specifically written or adapted for children to read for entertainment, imagination, moral learning, or literary appreciation.

2. Analyzing the Options:
• Picture books: These are storybooks where visual illustrations and text combine to tell a story. They are a classic form of children's literature.
• Myths and legends: Traditional stories about gods, heroes, and cultural folklore adapted for young readers to inspire imagination and teach cultural heritage. These are widely recognized forms of children's literature.
• Tales of heroes of history: Biographies and narrative historical stories meant to inspire children through real-life heroic figures. This is also a well-known form of children's literature.
• Thesaurus: A thesaurus is a reference book that lists words grouped together according to similarity of meaning (synonyms and antonyms). It is a language reference tool used for vocabulary building, writing, and editing, rather than a narrative or creative form of literature.

3. Conclusion:
Therefore, among the given options, a Thesaurus is a reference tool rather than a form of children's literature.
