The planet venus has a large amount of water vapor in its atmosphere, and like earth, has experienced extensive volcanic activity throughout its history. does this finding prevent the outside-in model from becoming a theory? why or why not?

yes, because venus is near earth and was likely affected by the same comets.
yes, because it shows that volcanic activity is necessary for a planet to have water.
no, because data taken on venus is not applicable to ocean formation theory on earth.
no, because a single observation on one planet is not sufficient to discredit a theory.
