Genetics problem?

 in a cross between two true-breeding plants, one with white flowers and another with purple flowers, the following F2 results were obtained: 925 plants with purple flowers, 288 plants with red flowers, and 387 plants with white flowers. Develop a hypothesis to explain the inheritance (mechanism) of flower color in these plant and analyze the data to determine if they fit the hypothesized mechanism.

What is the probable mechanism of inheritance of flower color in these plants?

A)Flower color in these plants is due to inheritance of one gene with a completely dominant allele.

B)Flower color in these plants is due to inheritance of one gene having an incompletely dominant allele.

C)Flower color in these plants is due to inheritance of two genes, each with completely dominant alleles.

D)Flower color in these plants is due to inheritance of two genes that show epistasis.

E)Flower color in these plants is due to inheritance of two genes that complement one another.
