What is one purpose of dialogue in a drama? to distinguish one character from another to allow actors to express themselves to present subtext or verbal irony to provide commentary on the story

Dialogue in a drama serves to present subtext or verbal irony, adding layers of meaning to the characters' interactions. Through carefully chosen words, characters can convey feelings, intentions, or hidden truths that may not be evident on the surface, enriching the audience's experience and understanding of the narrative. Additionally, dialogue is crucial for developing the story's thematic elements. It allows characters to voice their beliefs, conflicts, and emotional states, driving the plot forward while also revealing key insights into the world they inhabit. This interplay not only engages the audience but also invites them to reflect on the deeper messages woven throughout the drama.
