Science fiction lets us imagine stories that are not possible today such as human cloning and make us question what ethical and other problems would arise. 

Answer 2

The correct answer is C. Characters often face problems related to future technological advancements.

As the name itself says, science fiction is something made up (fiction) that has to do with science. Usually, the story is set in the future, or in space, so B is incorrect. A is also incorrect because the characters within science fiction are anything but ordinary - take Chewbacca from Star Wars franchise as an example.
