Here's why:
* Drama is specifically written for theatrical performance. It includes dialogue, stage directions, and often involves complex characters and conflicts.
* Fantasy is a genre of fiction that typically involves magical elements, mythical creatures, and fantastical settings. It can be adapted for the stage, but it isn't inherently designed for it.
* Historical fiction focuses on events set in the past. While historical dramas exist, not all historical fiction is intended for the stage.
* Realistic fiction aims to portray life as it is, without supernatural or fantastical elements. Like historical fiction, it can be adapted for the stage, but it's not a genre designed for it.
