Which of these modes of transportation would you most likely find in a science fiction story?

C. Spaceships

Science fiction is a form of literature that takes place in the future. Now, because it takes place in the future, all content is made up no matter how well or accurately based on current events it may be insomuch that the future seems logical, possible, and probable. The futuristic setting will have a heavy foundation in scientific advances (which is where the name "science fiction" comes from), and the setting will typically be in space or a distant world. As such, it makes the most sense that in a science fiction story, spaceships would be a common mode of transportation.
