carbon dioxide and water are the byproducts of complete combustion. Carbon monoxide(CO) is formed during incomplete combustion, or combustion that takes place in an oxygen-poor enviroment. Like oxygen, CO will combine with the hemoglobin in a person's blood and is less likely to release itself from the hemoglobin than oxygen. Explain the effect of CO exposure on the human body.

A Flower ranges from blue to pale blue to bright white. This plant is primarily pollinated by a bee that prefers blue flowers to white flowers. Blue flowers have a greater relative fruit set than the white flowers. Nevertheless, the percentage of different flowers colors remains stable in the study population from year to year. Which of these statements might explain this observation?

A)Reproductive Success does not affect evolution in this species.
B)The white flowers have evolved pollinator resistance
C)Fitness is primarily determined by fruit set in species
D)Flower Color is not heritable but is instead environmentally determined.

I am thinking it is D but not sure, please help.
