Answer:
A) CcSs
Step-by-step explanation:
In order to have all of the combinations both parents must have both dominant and recessive alleles for both traits. This is because the only time a recessive phenotype appears it must have two recessive alleles for that trait (genotypes such as ccss, or ccSS/ccSs if just recessive color, and CCss/Ccss if just recessive spots)
