Correct option is (a) Bottom

To explain I would say: The climbing film plate evaporator is designed to produce a thin film. In the climbing film evaporators, the feed is introduced at the bottom of the tubes and thus vapor due to evaporation expands which results in rise of the liquid along the tubes.
