One of the Factors That Help Animal- Pollinated Flowering Plants

One of the factors that help animal- pollinated flowering plants transfer pollen to plants of the same species is

A) pollinators are able to rapidly extract nectar from any species of flower,regardless of the pollinators' past or recent experience with a given flower type.
B) most pollinators broadly use many different types of flowers.
C) each species of pollinator typically visits flowers of one and only one plant species.
D) many pollinators have limited learning capacities and are most successful at obtaining food if they continue to visit the same type of flower after learning how to extract its nectar.
