Final answer:
The primary function and priority of stage lighting is to illuminate performers, which allows the audience to see the actors on stage.

Step-by-step explanation:
The number one function and priority of stage lighting is B. Illuminating performers. This foundational task allows the audience to see the actors and understand the action happening on stage. Beyond mere visibility, stage lighting has evolved to enhance the storytelling by creating ambiance and mood, enhancing set design, and reinforcing the perception of reality or artifice. A key aspect of stage lighting is the capacity to hide or reveal lighting fixtures, which influences whether the presentation appears realistic or acknowledges its theatricality.
Lighting design has become increasingly sophisticated, utilizing elements such as color, texture, intensity, shape, and movement to create a visual vocabulary that supports the narrative and guides the audience's focus. Skilled designers harness these elements to illuminate not just the performers but also the scenery, crafting a cohesive stage picture that adheres to thematic and architectural constraints, and controls the overall perceptions and emotions of the audience.
In certain cases, lighting design can serve as a scenic or costume element, altering the setting or appearance of a character merely through the application of light's properties. This highlights the significant role that lighting design plays in modern theatre, transforming it into another character that interacts with the script and contributes to the audience's experience.
