is it correct ???

Answer 2

The correct answer is 1.

The movie can be classified into either of three or more categories such as comedy, documentary or thriller. The other classifications are binary classifications as they only categorize their items into two categories.

A multi class classification assigns only one label to the items being classified.  Therefore a movie is either a comedy, thriller a documentary and not both.
