C. The trait for blue eyes is recessive, meaning that both parents must carry a recessive allele for their child to have blue eyes. If both parents have brown eyes, it means they both have dominant alleles for brown eyes, but they can still carry recessive alleles for blue eyes. When they have a child, there is a 25% chance that the child will inherit two recessive alleles and have blue eyes. This is the most likely explanation for the child in this scenario having blue eyes.
