The diagram shows two populations of toads. Population B formed after a few toads from population A were carried into a new environment. Based on the diagram, how might the toads in population B differ from the toads in population A after several generations?

• The toads in population B might have smaller eyes in order to see in the dark.

• The toads in population B might have a longer tongue in order to catch distant prey.

• The toads in population B might have darker skin in order to blend into their environment.

• The toads in population B might have brighter skin in order to attract prey.
