Answer: B The characters might fly in spaceships or have advanced technology.
Step-by-step explanation:
The characters might fly in spaceships or have advanced technology. This is the correct option.
These elements will be almost necessary to create a futuristic context or setting. If the characters took ordinary buses or trains and if they used fixed telephones or used the mail post, the story would reflect a real and old context. A futuristic setting should include elements ,technologically, much more sophisticated than the ones that really exist.
These options are not right:
-Only direct characterization would be possible ( The writer of a futuristic story can use this device. He / She can describe a character's emotions ,thoughts and actions).
-No theme would be possible because the future has not yet occurred. ( On the contrary, any theme can be developed in a writer's mind. It is the writer's creativity that makes fiction. This can be true- to -life or not)
