The correct answer is: all purple flowered plants.

According to the information given, the offspring of a complete dominance cross between two heterozygous purple flowers would result in all purple flowered plants. This is because the trait for purple flowers is dominant over the trait for white flowers. Therefore, even though both heterozygous parents carry one allele for purple flowers (P) and one allele for white flowers (p), the dominant purple allele will be expressed in all of the offspring.
