Tone refers to the attitude the author has towards the subject matter of a literary work. It is the writer's emotional or intellectual perspective on the topic at hand. It can be expressed through the language, word choice, or overall style of the writing. Tone helps create the overall atmosphere or mood of a piece of literature. It is an important tool for conveying the author's intended message or evoking certain feelings in the reader.

The other options you mentioned are different literary elements:

- A comparison between two otherwise unlike people, objects, or places is known as a metaphor. It is a form of figurative language that enhances the description by equating one thing with another.
- The time and place in which a story takes place is known as setting. It establishes the context and background of the story, helping to create a more immersive experience for the reader.
- The type of figurative language in which a non-human object is given human qualities is called personification. It is used to make the non-human object more relatable or to add depth and meaning to the description.
