Which is defined as a classification category used to identify specific type of literary work based on style structure or content.?

The classification category used to identify a specific type of literary work based on style, structure, or content is called a genre.

Here's why:

* Genre is a French word that literally means "kind" or "type."

* It refers to the distinct categories of literary works, such as poetry, drama, fiction, and non-fiction.

* Within these broad categories, there are further subgenres, like sonnets within poetry, comedies within drama, or historical fiction within fiction.

So, when you categorize a book as a "mystery novel," "science fiction," or a "tragedy," you are identifying its genre.
