Solution

The correct option is
A

50% purple and 50% white
When a heterozygous purple flower (Rr) is crossed with a recessive white flower (rr), the progeny obtained are with the genotype (Rr), (Rr), (rr) and (rr). So, 50% of the progeny are with purple flowers (Rr) and 50% are with white flowers (rr).
