What is the difference among these three words "kind", "sort" and "type"?

The word kind stands for having a relationship with the subject

Sort is only partly related

and type is a part of the subject

Explanation:

it is the background information on the characters and setting explained at the beginning of the story. the exposition will often have information about events that happened before the story began. the exposition is often the very first part of the plot.

choice 2 i like that prompt better.
