Answer:

C--One parent plant was heterozygous for flower color and the other was homozygous with purple flowers.

Explanation:

According to the question, is one parent plant was dominant for flower color and the other was recessive with purple flowers.

What is the expected ratio of purple to white flowers in the F2?

There was a 3:1 ratio of purple white flowers in generation F2 because the "masked" (recessive) genes from the F1 generation were allowed to pair, however they were only allowed to pair one time leaving the other three times to appear with purple flowers.

Thus, correct option is "C".
