Pines seeds are mainly small and winged, and are anemophilous generally, which means that the seeds are dispersed by wind. However, some seeds are larger and they have only a vestigial wing and are needed to be dispersed by a bird. Thus, If at high altitudes, birds become rare, the plants likely to disappear are Pine plants. Oaks are not generally found at such high altitudes.
So, the correct answer is 'Pine'.
