A gardener plants several flowering plants of the same species and notices that about 10% of the plants produce larger flowers than the others. He keeps track of the distribution of flower sizes over several years as shown in the table below. What explains these observations?
A. Random chance led to the distribution of flower sizes.
B. Overproduction of offspring resulted in more offspring deaths of the plants with smaller flowers.
C. Speciation occurred because variation was present in the population.
D. Natural selection occurred, causing a shift in the distribution of traits within a species.
I choose b? Is it correct?

D. Natural selection occurred, causing a shift in the distribution of traits within a species.
– This is the right answer.
You have chosen B, which is incorrect. B.
Overproduction of offspring resulted in more offspring deaths of the plants with smaller flowers.
– This is not the right answer because in the table you cannot find any over flowering data that implied in small plants during offspring season.
