A: self-perception theory doesn't address the effects that our
    behaviors have on our expressed opinions

    Incorrect.
Self-perception is defined by Myers (pg 157) as "the theory that when unsure of our attitudes, we infer them much as would someone observing us-- by looking at our behavior and the circumstances under which it occurs."  Choice A is incorrect, because self-perception does address the effects that our behaviors have on our expressed opinions.  Self-perceptions states that we use our behaviors, which are easily observable to the individual, to infer our attitudes, which are not observable to the individual.   Because both self perception and dissonance do account for the effects that our behaviors have on our expressed opinions, choice A is incorrect.
