B) parasitism.
C) character displacement.
D) a predator-prey interaction.

This is an example of character displacement, where two species evolve to differ more in traits that overlap in their ranges, in order to reduce competition for resources such as nectar. In this case, the difference in tongue length would allow for each species to access different parts of a flower's nectar, reducing competition for that resource. The other options (seed-dispersal mutualism, parasitism, predator-prey interaction) do not accurately describe this scenario.
