Answers;

B. The flower color in a population changes over time.

Explanation;

• Phenotypic traits or changes are observable traits or characteristics of an organism, for example hair color, weight, or the presence or absence of a disease. Phenotypic traits are not necessarily genetic.
• Genotype is a set of genes in the DNA and are responsible for a particular trait while phenotype is the physical expression of that trait. Genes inherited from the parent organism determine the traits displayed by an organism.
