Gentian is a flowering plant that is native to Europe. The plant can have either red, yellow, or orange flowers. The flowers of
these plants are pollinated by three species of bumblebees. Species 1 and species 2 visit orange and yellow flowers. Species 3 visits plants with only red flowers. Which is a likely advantage of having three different-colored varieties within a population of gentian plants?
A It allows the species to produce a large number of seeds after pollination.
B It allows the plant to attract pollinators other than bumblebees for pollination.
C It ensures that the species will survive even in the absence of a specific pollinator.
D It ensures that the flower can self-pollinate in the absence of pollinators.
