Ais a director whose films are marked by a consistent, individual style, and is closely involved in conceiving the idea for the film's story and writing the script.

The correct answer is auteur.
It is a French word which means 'author,' and it refers to directors who are different from other mainstream directors, but rather have quite distinctive and highly individual style of creating movies. Usually, they are less known, indie directors, but still very good.
