A plant is homozygous for flower color. Its flowers are pink. Which conclusion is best supported by the information?

I think it would be that both parents had an allele for pink flower color because the trait could either be dominant or recessive but the question doesn't say.
Answer:
Your answer would be C : Both parents had an allele for pink flower color.
Explanation:
When both parents provide the same allele of a gene, the offspring is h o m o z y g o u s for that trait. In this situation, C would be correct because the information states that the plant is h o m o z y g o u s and choice C fits.
I spaced out a word since it was apparently inappropriate.
Also, Option C is correct on Edg.
