Answer:

The correct answer would be B. Neither purple flowers nor white flowers are dominant.

It can be explained with the help of codominance.

Codominance is a situation in which both the alleles of a gene are equally dominant and express themselves completely in a heterozygous condition.

For example, in ABO blood group system allele [tex]I^{A}[/tex] and [tex]I^{B}[/tex] are codominant while [tex]i[/tex] is recessive.

Similarly, in the above experiment purple and white flower color trait are codominant or we can say that neither is dominant over each other.
