If you cut the optic nerve of a newt, what happens?

    *a.    The fibers grow back and attach to their original targets, resulting in normal vision.
    b.    The fibers attach to multiple targets, resulting in blurry vision.
    c.    The newt remains blind, since neurons do not regenerate.
    d.    The fibers grow back and attach to random targets, so they see a scrambled picture.
