Final answer:
The correct answer is option d) Designing stage lighting.
Step-by-step explanation:
The role of a professional dramaturg typically includes several crucial tasks that are integral to the production of theatre. These include advising on historical accuracy, analyzing script themes and structure, and potentially assisting with casting decisions.
However, designing stage lighting is not traditionally within the purview of a dramaturg. This task is generally reserved for a lighting designer, whose job is to creatively illuminate the actors and the stage in a manner that enhances the themes, actions, and dramatic arc of the piece.
While a dramaturg may inform the cultural and thematic aspects that could influence lighting design, the technical and aesthetic execution of stage lighting is a separate, specialized role.
