A bee lands on a flower to collect nectar needed to make food. Pollen from the flower sticks to the bee's body. The bee then flies to another flower to collect more nectar. While there, the pollen from the first flower rubs off, pollinating the plant. This allows the plant to reproduce. Which type of relationship does this represent?
A. mutualism B. parasitism C. Commensalism D. competition
A. mutualism
