What does "screenplay adaptation" mean?

Screenplay adaptation refers to the process of converting a book or another source into a film script, making option B the correct answer. This process involves taking existing narrative material—such as novels, short stories, plays, or even other films—and restructuring them into a format suitable for film. This can include changes in dialogue, character development, and plot pacing that align with the visual storytelling medium of cinema.

In screenplay adaptation, the original source often serves as the foundation, but it is important to note that the resulting screenplay may differ significantly from the source material in various ways, including condensing plots or altering characters to fit the film's runtime and production needs.

The other options focus on different types of adaptations that do not align with the specific definition of a screenplay adaptation in the context of cinema. For example, using a film script as a basis for a video game is a different process entirely, as is transforming a screenplay into a theater production, which involves a reinterpretation rather than an adaptation. Similarly, adapting comic books into movies is a specific subset of adaptation but does not encompass the broader and more common practice of adapting literary works into screenplays.
