Answer
The production of pink flowered plants from a cross between a red flowered plant and a white flowered plant is an example of C. incomplete dominance
Step-by-step explanation
Incomplete dominance is a type of intermediate inheritance that occurs when one allele for a particular characteristic is not completely expressed over its paired allele. The phenotype that is formed will have a physical trait which combines the phenotype of both the alleles. In this example, the pink flowered plant is the resultant phenotype which is different from the paired allele in the red flowered plant and white flowered plant.
