Many Salmon Return to the Place Where They Were Born

Many salmon return to the place where they were born to lay eggs. You hypothesize that they use visual cues to find their way back. To test your hypothesis, you blind salmon and then examine whether or not they are able to return to their birthplace. You find that they are unable to find their way back. From this experiment, you:

A) have proved your hypothesis.
B) have rejected your hypothesis.
C) supported your hypothesis.
D) can't determine whether your hypothesis is supported or not.
E) developed a theory about the role of vision in salmon navigation.
