If both parents are chinchilla (ccᶜʰᶜʰ), then they can only pass on a recessive chinchilla allele to their offspring. Therefore, full coat color (CC or Cc) is not possible in their offspring, as it requires at least one dominant full coat color allele. Chinchilla (Ccᶜʰ or cᶜʰc) and Himalayan (ccʰ) coat colors are both possible, as they only require recessive alleles. Albino (cc) is also possible, as it is the only possible genotype with two recessive alleles. Therefore, the correct answer is A) full coat color.
