Some moles have eyes that are so reduced that they function only minimally in light perception. Some snakes have hind-limb bones that are reduced completely to nonfunctional remnants. Which of the following might be a plausible evolutionary argument for the reason structures like these become minimized?

    Structures are minimized through disuse by an individual to the point of becoming nonused or rudimentary, and these nonused structures can then be passed on to the offspring.
    Individuals who have inherited a minimized nonuseful structure may actually have an advantage over individuals that have the structure because possessing it may cause them to be less "fit" in their environment or be a less successful reproducer.
    Individuals purposefully cause mutations to occur to minimize nonuseful structures, because they may be potential sites of infection or parasitism.
