A)homozygous dominant purple pea plant and homozygous recessive white pea plant
B)homozygous dominant purple pea plant and heterozygous white pea plant

The 3:1 phenotypic ratio is consistent with a cross between two heterozygous purple pea plants (Pp x Pp), where P is the dominant allele for purple flowers and p is the recessive allele for white flowers.
