Final answer:
A shared theme or argument best represents the main idea in both the letter and the film, as a theme is the central, unifying concept of a story.

The best option that captures the main idea apparent in both the letter and the film is (a) A shared theme or argument. This is because a theme is the unifying idea behind a story, film, or any piece of literature that connects plot points, conflicts, and characters to a major concept, often providing insight into humanity, life, or the universe.
If both a letter and a film share the same main idea, they convey the same message, making a shared theme the element that ties them together.
